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 ar-
ticle describes the research of PHU thermal load using mathematical simulation in Sim-
ulink / Simscape environment.
Methods of thermal load estimation are based on the
Schmidt method of finite differences.
The results of the PHU operation dynamics re-
search 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 calcu-
lation of the cooling system are given.
Keywords
: vehicles, pneumatic/hydraulic springs, cushioning system, experiment, run-
ning smoothness, heat-load, Schmidt method of finite difference, Simulink, Simscape,
SimHydraulics.
