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.
