Opis:: Owing to the optimized growth technology of the 1-2 nm calcium fluoride films on n-(111)-silicon, metal/tunnel-insulator/semiconductor phototransistors have been fabricated by the molecular beam epitaxy at the temperature 250°C. The characteristics of these transistors were measured in a wide range of voltages, and the proofs for current gain were found throughout the investigated range. The gain value exceeds $10^3$ approaching the theoretically estimated value in this system. The stability and reproducibility of the device characteristics were satisfactory. The results support the candidacy of calcium fluoride for being a vital dielectric in silicon-based functional electronics.

Opis:: Absorption and reflectivity measurements were carried out on Zn$\text{}_{1-x}$Mn$\text{}_{x}$Se:Ni solid solutions. The spectra demonstrate the radical change of the structure of internal Ni$\text{}^{2+}$(3d$\text{}^{8}$) transitions at the presence of the Mn ions and strong dependence on Mn concentration. The threshold energy ħω$\text{}_{th}$ for the process of Ni photoionization to the valence band Ni$\text{}^{2+}$(3d$\text{}^{8}$) + ħω$\text{}_{th}$ → Ni$\text{}^{1+}$(3d$\text{}^{9}$) + h is shifted to the lower energy by 30 meV, but hardly depends on x despite the essential increase in the energy gap.

Opis:: The purpose of this study was to develop a model for an integrated estimation of the functional state of the human organism (FSHO) and an integral estimation of physical factors (PF) for hygienic rating. Tests were performed twice with 3 men in 0.7-clo clothing during 4-hr mental work with 9 combinations of 4 PF: wideband noise (55–83 dB(A)), whole-body vibration (6 Hz, az =0.2–1.8 ms−2), air temperature (18–30 C), and illumination (1, 3, 5 lx). Thermoregulatory, cardiovascular, and psychophysiological reactions and temporary threshold of hearing (TTS2) shifts were studied. For the integral estimation of PF influence on FSHO the model F(y1, y2, ... ym) = f(x1, x2, ... xn) was used, relating both FSHO and PF sets. The most important physiological parameters in creating FSHO are defined and the contribution of individual parameters of FSHO and PF is found.

Opis:: This article describes original method proposed by authors that provides decreasing of dynamic loading of tractor’s powertrain by means of change of reactive element torsional stiffness. In tracked vehicles one of the most loaded elements is final drive unit which loaded by high dynamic modes. In tractor Chetra 6C-315, final drive is epicyclic where stopped element is ring gear. Authors propose using of strictly resilient (5 degrees in forward-backward direction) mount of ring gear instead of stiffening. Design study of installation between hub and gear ring that connects drum and crown gear, of the resilient metal plates pack was performed. This pack is kind of elastic coupling. Resilient packets of coupling sustain loads and smooth over peak dynamic loads and after elastic deformation of these packets rigid coupling between hub and coupling crown is provided at contact surfaces of skewed stops of hub and crown. To analyse efficiency of proposed method of dynamic loadings decreasing of powertrain elements three-dimensional model of powertrain was created in “Universal Mechanism”. In addition, solid model of caterpillar mover was created in the same software for analysis of influence on powertrain loadings of complex of kinematic and dynamic factors influencing forming of torque on driving sprockets. This article presents results of modelling of loading processes in powertrains elements with elastic coupling and without it during longitudinal motion at various speeds and in turns with various radii. Results show that elements dynamic loading at high loading dynamic modes in case of installed coupling is decreased by 20-30%.

Opis:: This paper is devoted to describing of method of decreasing of vibration load level on tractor operator’s working place by means of using of vibrations dynamic dampers in cabin suspension (on other words – dynamic absorbers of dynamic vibroisolators). Standard cabin vibroisolators of tractors DT and VT series include monolith rubber block and have limited capabilities to change its elastic parameters adaptively during impact of vertical and lateral vibration loads with various frequencies. Elastic-damping properties of these vibroisolators does not allow to provide comfortable conditions for operator work because their abilities of vibration damping are not enough especially at low-frequency vibrations. Dynamic vibration dampers installed in cabin suspension were proposed by authors for decreasing of vibration load level on operator workplace. These dampers include additional masses connected to main mass due to elastic-damping elements. Several variants of dynamic vibroisolators schemes were proposed by authors. These schemes differ in quantity of additional masses (one, two or three) and type of connection between additional masses and main mass due elastic-damping elements (parallel or in series). Three-dimensional model of caterpillar chassis, suspension, engine, cabin and operator’s seat of tractor was created in software “Universal mechanism” for performing of computational research. On this model, researches of vibration of sprung mass were made for tractor motion with and without hook load at 3rd and 7th gears on smooth surface and on testing areas with single, periodic and random bumps. Research results indicate undoubtedly best vibroprotective properties of cabin’s suspensions with dynamic vibroisolators.
