The research of the pneumatic/hydraulic unit (PHU) internal dynamics is very urgent task. The research of heat load is of particular importance since it is thermal stress of cushioning system components that determines the performance of the structure. The article describes the research of PHU thermal load using mathematical simulation in Simulink/Simscape environment. Methods of thermal load estimation are based on the Schmidt method of finite differences. The results of the PHU operation dynamics research are presented. The results of simulation are shown and compared with the results of bench tests of a light weight tracked vehicle PHU. The recommendations for the calculation of the cooling system are given.
