Opis:: During the moving of vehicle is a change in temperature mode, which arises due to fluid friction in the dissipative element (throttle bores) hydropneumatic spring. In this case, hydropneumatic spring can be warm to significant temperatures. Due to lower viscosity of the fluid below the warning level, the increased heat causes a sharp increase in various types of leakage, increased friction parts, and as a consequence, the intensive wear and seizure of the surfaces. This leads to partial or complete loss of efficiency hydropneumatic springs. To changes in temperature mode in the hydropneumatic spring is influenced not only the external surface of the hydropneumatic spring, temperature and speed of blowing air flow, but also the conditions and the duration of the moving of vehicle. In this paper we investigate the heat intensity of the hydropneumatic springs of vehicle in weight 5.5 tons during the moving at different speeds for different types of roads. Investigations were carried out on the basis of mathematical models realized in a package of Matlab Simulink. In this case, was fixed the time average power released in the hydropneumatic spring in the form of heat. According to the research conclusions were drawn about the most heavy-duty vehicle and the amount of heat generated by the length of relative motion in this mode. To prevent overheating, an algorithm diagnosis of the condition and management of heat intensity of the hydropneumatic springs Also made recommendations to reduce the heat intensity hydropneumatic springs.

Opis:: There is presented an effect of the changes of the concentration of magnetic particles included in the ferro-oil on its dynamic viscosity in the presence of external magnetic field in this paper. The study was conducted in the context of temperature’s changes. The authors assume that the concentration of magnetic particles in ferro-oil can significantly affects its basic physical properties as dynamic viscosity, as well as the operational properties of journal sliding bearings ferro-oil’s lubricated. The equally significant as the above mentioned properties may affect the external environmental conditions of operation, especially temperature changes. In this context, an important technique’s issue appears to determine the principles of selection of optimal concentration of above mentioned particles according to the existing environmental conditions of its operation, or the expectations laid against the operation of the devices. Rheological studies were carried out on Physica MCR 301 rheometer in the “plate-to-plate” measurement system with an adapter to magneto-rheological studies MRD 180/1T. Thermal stabilization was carried out by a water jacket in a closed chamber and controlling the nature of the magnetic field was conducted by current’s changes. Tests were performed for four selected temperature range of 60º, 70º, 80º and 90ºC as regards changes an external magnetic field intensity 0-700 mT. The selected concentrations of magnetic particles in a ferro-oil were 1, 2, 4, 6 and 8%.
