Opis:: This paper provides characteristics of the evacuation and technical rescue heavy vehicles. Heavy tactical evacuation and technical rescue vehicles are built on the chassis of tactical vehicles with high loading capacity, generally with8x8 driving system. In each analysed case, the vehicles are one of the family members of the tactical heavy-duty vehicles. Evacuation equipment of such vehicles is as follows: main winch, arm or towing device, and lifting equipment. A domestically manufactured vehicle, developed under the project No. 356/BO/1, was presented. The testing process that such type of vehicles, including the above mentioned, are subject to have been discussed herein. Revision of parameters received and as specified in the requirements and relevant standards enforces an adequate scope of testing. In the case of the MAMUT vehicle, the following requirements have been checked: structural design, engine, driving system, cab, main winch, auxiliary winch, winch for self-recovery, hydraulic crane, hydraulic hoisting and towing equipment, power generator, electrical system, safety, ergonomics and technical aesthetics, specialist equipment, secret camouflage, and transportability.

Opis:: The article presents issues concerning the analysis of one-dimensional traction signals describing energy conversion processes in driving systems of electric traction vehicles. The method of FFT analysis has been compared to the wavelet method. The most crucial tasks have been discussed of wavelet analyses of signals connected with the problems of drive modelling. Fundamental tasks of coefficient analyses such as approximation, compression and denoising have been taken into account, as well as more complex tasks such as filtering band component and feature extraction. An example of analysis of current signal from tram driving system obtained in the conditions of tractive adhesion failure has been presented. A hypothesis has been demonstrated that coefficients obtained in subsequent stages of wavelet decomposition can constitute the basis for indicating electric current feature vector for the phenomenon of adhesion failure. Application has been proposed of simple characteristics of transform coefficients such as energy, number of zero transitions and power. A feature vector of coefficients has been chosen. A method of feature classification has been proposed in order to implement it in adhesion failure recognition. The results of verification of wavelet analysis application in adhesion failure recognition have been presented. As tance has been taken as to the results of the diagnosis taking into consideration currently used anti-slip systems of traction vehicles.

Opis:: This article shows function and construction assumptions of mobile, wireless inspection-cleaning robot of ventilating pipes. Robot has got cordless colour camera. Robot has got many different sensors (flow and direction of air, gas, humidity and temperature) it can exactly diagnosed canal in respect of efficiency and presence of fire or gas. Robot arm is equipped in four changeable endings: clutch with pincer, taking in shovel, two traverse brushes (deaning ventilation canals about square or rectangle section) and brush about oblong pivot (cleaning ventilation canals about circled section). Thanks to changeable endings robot can fast become inspector from a cleaning machine. Helping vertical tighten wheel is a innovation introduced to the robot construction, in result it increases wheels tighten to the ground. It will decrease wheel skid and it make possible to drive under larger inclination or in vertical canal. Tighten power vertical wheel to over head partition of ventilation canal is regulated by the tighten sensor. This article shows modelling construction elements of the robot. In certain domains work, the elaborated robot exceeds with functional quality industrial robots by using in it several environmental sensors and innovations.
Artykuł przedstawia założenia funkcyjne i konstrukcyjne mobilnego, bezprzewodowego robota do inspekcji i czyszczenia kanałów wentylacyjnych. Robot wyposażony w kolorową kamerę przekazuje obraz bezprzewodowo. Wzbogacony o różne czujniki (min. przepływu i kierunku powietrza, gazu, wilgotności i temperatury) może dokładnie zdiagnozować kanał pod kątem sprawności oraz obecności gazu lub ognia. Ramię robota jest wyposażone w cztery zamienne końcówki: chwytak ze szczypcami, łyżkę nabierającą, dwie szczotki poprzeczne (czyszczenie kanałów o przekroju prostokątnym lub kwadratowym) oraz szczotka o osi podłużnej (czyszczenie kanałów o przekroju kołowym). Dzięki wymiennym końcówkom robot może szybko przeistoczyć się z inspektora w maszynę czyszczącą. Wspomagające pionowe koło dociskowe jest innowacją wprowadzoną do konstrukcji robota „Inspektor l" w celu zwiększenia docisku kół do podłoża. Zapewni to zmniejszenie się poślizgu kół oraz możliwość jazdy pod większym nachyleniem lub w kanale pionowym. Siła docisku koła pionowego do górnej ścianki kanału wentylacyjnego jest regulowana za pomocą umieszczonego w konstrukcji czujnika nacisku. W artykule przedstawiono zamodelowane elementy konstrukcyjne robota.

Tytuł:: The effect of automotive vehicle braking system failure on driving safety
Autorzy:: Kowalski, M.
Powiązania:: https://bibliotekanauki.pl/articles/244871.pdf
Data publikacji:: 2013
Wydawca:: Instytut Techniczny Wojsk Lotniczych
Tematy:: car diagnostics

Opis:: The paper describes systems responsible for driving safety of vehicles weighing up to 3.5 t. It is focused on selected failures (fouling) of braking systems that are typical during motor cars operation. Simulation testing regarding effect of selected failures (fouling) of braking system elements on braking force and braking efficiency were performed. In order to perform such testing, author of the paper worked out the methodology of testing which is also described here. The test results (partial) are displayed as tables and charts. The negative effect of selected failures on braking force and braking efficiency index is influencing directly on motor cars driving safety. It is also emphasized that it is important to maintain and observe automotive manufacturers’ technical requirements regarding braking system elements such as tyre pressure, tyre tread condition, brake shoes wear, etc. Basing on the test results it is found that excessive wear of tyres and brake shoes wear could be the reason of significant WSH index decrease resulting in faulty car. This can be visible through lower than allowable level of braking efficiency index WSH, which is the basic legal diagnostic parameter of break system condition assessment. Replacing such elements significantly improves braking efficiency index WSH.

Opis:: Digital tachographs as devices recording the work of a lorry and driver’s work are a constant factor in the work of a professional driver. It is therefore important to preserve the security of recording and storing electronic information. In this matter, cryptography also becomes an inseparable field of science. The control services set up to conduct roadside inspections do not detect all violations in the recording devices by encrypting information in information systems. One of the frequent vehicle operating parameters that can be falsified are the speed of the vehicle and its rotational speed, as well as the time and efficiency of the driver’s work. These parameters affect the amount of fuel consumption. The reduction of fuel consumption translates directly to the reduction of harmful substances emitted by the car to the environment. Variable compression engines are becoming the future of motoring in the case of internal combustion engines. It is noticeable that there are more frequent deliberate of regulations; and more violations rules concerning the proper functioning of recording devices by recording driver activity. Current methods of preventing violations are insufficient. The article points out the violations related to the actual rotational speed of the crankshaft of the internal combustion engine in relation to the vehicle speed profile, which is directly related to the fuel consumption and the emission of harmful substances. The article describes the ways to reduce fuel consumption, of which the correct driving technique is important in addition to the previously marked parameters. The factors that increase the awareness of professional drivers in the aspect of proper driving techniques are described.
