Abstract
In order to obtain a thermodynamic model of a hydraulic shock absorber which contains much more information and is much more realistic than the traditional model,the research is carried out through introducing the stochastic uncertainty theory into the traditional thermodynamic model of the hydraulic shock absorber.The hydraulic oil density,thermal conductivity,specific heat capacity and kinematic viscosity are taken as random variables.The stochastic thermodynamic model of the shock absorber is established with the algebra synthesis method of function digital characteristics and the laws of heat-transfer process about oil are obtained.The results of the stochastic thermodynamic model and the traditional model are compared with experimental results.The research shows that the introduction of the stochastic uncertainty theory is feasible and the stochastic thermodynamic model is superior to the traditional model.关键词
