摘要：

A shock absorber thermodynamic model was built through the conservation of energy equation and first law of thermodynamics after detailed analyzing its heat generation and transfer mechanism. These equations were solved to obtain the evolution of the temperatures of the shock absorber during the test time. And the temperature of simulation were measured to compare with the model and to validate it. The results show that the more influential correlations are the internal flow convection correlation used between the oil of the different chambers and the tubes of the shock absorber and the external flow convection correlation between the outside tube of the shock absorber and the ambient air.
