Study on Thermal Dynamics Modeling and Simulation of Inflatable Shock Absorber

Aiming at problems such as high temperature rise of the shock absorber, which may easily lead to seal damage, the mono-tube type shock absorber was the research object, and theoretical modeling study of thermodynamics was carried out. The changes in the internal energy of the system and the energy exchange with the outside world were deduced through engineering thermodynamics, and the heat transfer coefficient of each surface of the cylinder tube was derived through the theory of heat transfer, especially the analytical expression of forced convection heat dissipation was clarified. The viscosity-temperature characteristic of the oil was analyzed, and the thermal equilibrium temperature of the shock absorber and its influencing factors were simulated and analyzed through programming, which provided theoretical basis for the design and optimization of the shock absorber parameters.
