Opis:
Purpose: The paper discusses selected aspects of the use of polymeric materials in the construction of ring springs. Design/methodology/approach: Special attention is paid to differences in characteristics of such materials in comparison to springs made of traditional material - steel. Findings: The result of the work is a static-dynamic model of polymer ring springs. An analysis of the influence of friction on the performance characteristics was carried out. The results of the preliminary experimental studies confirm the correctness of the model. Practical implications: Analytical models have been developed, as tools to support the design processes of ring spring structures, in the field of innovative material solutions. They are a tool for the selection of geometric and material characteristics of springs, meeting the set operational expectations. Originality/value: Extensive possibilities in the selection among a group of structural polymer materials allow the formation of structural solutions with a variety of characteristics, both elastic and impact or damping. The area of application ranges from mechanical engineering to construction or transportation. The characteristics complement the possible field of solutions in cases of use of traditional metallic materials, especially high-grade steels. Material solutions make it possible to achieve significant economic effects in addition to unavailable performance characteristics, both static and dynamic. These are due to competitive prices for polymer materials, including composites, and manufacturing costs. They open up a wide field for utility innovations.

Opis:
In order to investigate the evolution trend of rail corrugation under the action of slip and interface effects, stick-slip vibration characteristics of a wheel-rail system in different line con- ditions have been analyzed in detail by establishing a complete three-dimensional coupling metro vehicle-track numerical model and considering the friction memory effect characteriz- ing the slip rate and state dependence as well as interface effect. The results show that on a straight line, the friction memory effect has less influence on the wheel-rail contact stick-slip characteristics, and the values and variation ranges of adhesion coefficients and creepages are relatively small, indicating that it is difficult for the wheel-rail system to have stick-slip vibration, which makes it less likely to form rail corrugation. On a curved line, the fluctua- tion amplitudes of the inside longitudinal stick-slip characteristics and the outside transverse stick-slip characteristics are relatively large, which illustrates that the inside wheel-rail sys- tem is more prone to stick-slip vibration in the longitudinal direction, while the outside wheel-rail system is more prone to stick-slip vibration in the transverse direction, thus lead- ing to different forms of rail corrugation. The friction memory effect reduces longitudinal and transverse creepages of both the inside and outside wheel-rail systems, demonstrating that the friction memory effect can moderate the relative wheel-rail slip and thus reduce the development rate of rail corrugation. The interface effect makes longitudinal and transverse adhesion coefficients of the wheel-rail system tend to homogenize and mostly decrease, while the corresponding creepages tend to increase. Although an increase in the creepage induces an enhanced interface slip, a smaller adhesion coefficient does not cause a significant change in the corrugation evolution. Friction memory and interface effects can cause the wheel-rail contact adhesion area ratio to increase, thus making the contact stick-slip distribution tend to homogenize, which is beneficial to reduce wear in the contact area and promote wear to homogenize.

Refill friction stir spot welding (refill FSSW) was used to weld 3.2-mm-thick 2060 aluminum alloy. Joint formation, defect characteristics and tensile-shear property were analyzed. Results show that keyhole can be completely eliminated under different plunge depths. However, defects such as void, unconnected welding, hook can be observed under the plunge depths of 3.4-4 mm.The size of the overall void initially increased and then decreased with the increase of the plunge depth, while the void was the smallest under the plunge depth of 3.4 mm. The unconnected defect at the lap interface gradually shrank a welding line from obvious crack. Different hook morphologies were observed under different plunge depths. The tensile-shear load of joint increased with the increase of the plunge depth and was up to the largest under the plunge depth of 4 mm. All the tensile-shear specimens fractured along the lap interface. Compared with the void, the unconnected defect had a greater influence on the tensile-shear property.

Opis:
This paper expands the M-K curve theory with examples of the most commonly mentioned pile-soil mechanics behaviours in the literature and their corresponding κ 2 variations. A brief introduction shows the history of the Meyer-Kowalow theory and its basic assumptions. This is followed by the relationship between in situ investigation CPT results, with parameters C1, C2, Ct used to approximate the load-settlement curve according to the M-K theory. The Meyer-Kowalow curve satisfies asymptotic behaviour for small loads, where linear theory applies, and for limit loads, when pile displacement is out of control. Essential in the description are constant parameters C, which refer to the aggregated Winklers modulus, Ngr limit loads and k, which is crucial for static load test results. For this reason, the authors sought to calculate the κ value based upon soil mechanics principles. This article shows methods for checking statistical mathematical calculations, published earlier by Meyer using CPT investigations. It presents real case calculations and directions for future planned research.

Opis:
Refill friction stir spot welding (RFSSW) was used to weld the 2060 aluminum alloy with 2 mm thickness. Joint formation, defect characteristics and mechanical properties were investigated. Results show that stir zone (SZ) is clarified into dynamic recrystallization zone (DRZ) and heat extruded zone (HEZ) due to different microstructural features. The size of void near the hook tip decreases with the increase of the plunge depth. Different hook morphologies are obtained under different plunge depths. The tensile-shear load of joint with the void defect initially decreases and then increases with increasing plunge depth. The mean loads of joints under different plunge depths are in the range of 5.1-5.8 kN. The void separates the hook from lap interface, so the cracks initiating from the hook propagate along the sleeve retreating path. The hook has a larger influence on the tensile-shear load of joint than void. All the tensile specimens present a shear-plug fracture mode.

Opis:
This paper presents disc brake surface temperature field measurements, during emergency braking in real industrial conditions, by means of the thermovision infrared camera. The temperature field assessment enables the verification of the numerical modelling of the brake performance in the succeeding step. The experimental part of the research also covers tribological testing on the coefficient of friction between the friction brake material (brake pad) and steel (brake disc) in laboratory conditions on a tribotester which satisfied the similarity criteria with the mine winder hydraulic disc brake. The tribological characteristic of the friction couple, including the kinetic and static coefficients of friction, were determined for use in the finite elements analysis (FEA) of the brake thermo-mechanical instability (TMI) problem. In the numerical part of this work, the FE modelling technique was used to simulate the brake interface hot spotting and the axial disc distortion as a function of the geometrical and material properties of the brake elements and the brake’s operational conditions. The critical speed above which TMI would occur was calculated for the analysed mine winder brake system. A FE method was used to find the temperature distribution and the resulting thermal stresses and distortions in the brake discs. The disc division into various numbers of sections was numerically tested for the division’s effect on thermal stress reduction and axial distortions.
Artykuł przedstawia wyniki badań rozkładu temperatur na powierzchni tarczy hamulcowej w czasie hamowania awaryjnego maszyny z użyciem kamery termowizyjnej. Uzyskane wyniki umożliwiły weryfikację obliczeń numerycznych tego procesu hamowania. Przedstawiono także badania tribologiczne charakterystyki ciernej pary hamulcowej, czyli materiału okładziny hamulcowej i materiału tarczy hamulcowej. Badania tribologiczne wykonano na stanowisku spełniającym najważniejsze kryteria podobieństwa do hamulca tarczowego maszyny wyciągowej. Uzyskane wartości współczynników tarcia kinetycznego i statycznego były wykorzystane następnie w modelowaniu numerycznym termomechanicznej niestabilności analizowanego hamulca i wyznaczeniu krytycznej prędkości początkowej, powyżej której system staje się niestabilny. Obliczenia numeryczne obejmowały także wyznaczenie naprężeń termicznych w tarczy, deformacji osiowej tarczy oraz wpływu podziału tarczy na segmenty na naprężenia i jej deformacje osiowe.

Opis:
Attempt to raise train speed involves application of greater braking power i.e. braking systems rapidly absorbing and dispersing stored heat energy. To maintain high efficiency of braking system in the whole operational process, it is necessary to control the friction set: brake and pad before reaching limitary wear particularly of friction pads. Stable and constant - in the whole speed range- coefficient of friction "mi" and realization of greater pad's pressures to the disc because of better conditions of warmth offtaking generated during braking into the athmoshere are basic advantages of disc brake systems [8]. Few disadvantages of disc brake include a lack of possibility of controlling the condition of the friction set: brake and pad in the whole operation time. It is particularly observable in rail cars, where disc brakes are mounted on the axle of the axle set between the wheels. To check the wear of friction pads and brake discs it is necessary to apply inspection channel to carry out inspections, and to carry out replacement of friction parts in case they reach their limitary wear. The purpose of this research is to apply vibration signal of pad calipers to assess the wear of friction pads of disc brake by defining characteristics of time, amplitude and selected frequency characteristics during tests at internal brake station.

Opis:
In the paper, at first some remarks concerning friction are presented by the definition of the friction itself, as well as its essential force characteristics. An adequate definition of friction is introduced, and moreover a correct its characteristics. Next the statics, dynamics, and kinematics of the friction system is given, forming the force characteristics of this system for each of the mechanical behaviours, taking into account real inertia forces of the body under friction. Three types of coefficients of sliding friction have been separated, namely: coefficient of static friction, dynamic friction, and kinematic friction. Then the comparative analysis of existent and new knowledge on the force characteristics of friction process has been presented. The consideration on how to determine the coefficient of static friction has also been carried out. Reflections on the possibilities to form further force characteristics of the friction process are presented to develop this work with some final remarks directing the attention on the conditions of development of science on friction.

Opis:
The publication presents the results of measurements of the operating parameters of the drum drive of a belt conveyor operating in a copper ore mine. The laboratory and industrial tests of belt conveyor components so far have largely focused on idler sets, the belt and the conveyor route. The authors of the publication notice that the subject literature lacks information on research into the coefficient of friction between the belt and the drum in an industrial facility under real conditions, which may imply that the phenomenon of driving force transmission from the drum surface to the belt has not been thoroughly explored. The investigations described in the publication were aimed at determining the kinetic coefficient of friction between the conveyor belt and the lining of the drive drum under operating conditions. In the first part of the study, preliminary laboratory tests were carried out, whereas in the second part of the study, a mobile, non-invasive measurement system was applied, which allowed for recording the kinematic and dynamic parameters of the conveyor’s operation. During the several dozen minutes of the conveyor’s operation, there were several start-ups and brakings as well as periods of steady operation under variable load on the material handled. The non-typical planned sequence of switching on the drive motors caused a temporary slip of the belt on the drive drum surface during one of the start-ups. The recorded parameters of the conveyor operation enabled determining the operational limit value of the friction coefficient between the belt and the lining of the drive drum.

Opis:
The paper presents the results of measurements of friction forces achieved by forcing slip between a poly-V 5pk belt and the pulley needed to formulate empirical models of dynamic friction. This kind of belt and pulley can be found in automotive industry to drive the alternator and coolant pump in cars. The forces were measured for several cases of assumed preload and two cases of wrap angle. The complicated stick and slip processes are simplified by assuming an average effective dynamic friction coefficient. The results show that the values of friction cannot be described by classic Euler formula. They not only depend on the velocity, but also noticed that can depend on sign of acceleration. Also, some results of the approximation are presented. It is proposed that the assumed norm will be minimised using the Nelder-Mead optimisation method. The measurements and the approximation let assume specified dynamic friction characteristics. The achieved results are applied to the model of a belt transmission. In the paper presented results of simulations of the model of belt transmission.
