ABSTRACT
Aiming at the vibration reduction system widely used in suspension systems of heavy machinery, trains and automobiles, the effects of elastic modulus and viscosity of shock absorber oil on the stiffness of hydraulic spring are studied. Based on the basic theory and method of fluid-solid coupling analysis, four working conditions simulation models of two kinds of methyl silicone oil are established by using finite element software of ADINA, and the dynamic characteristics of shock absorber stiffness are calculated. The theoretical analysis and simulation results show that the liquid compressibility and viscosity have obvious influence on the liquid stiffness and the reliability of the shock absorber, which provides a good technical support for the engineering design and application of the shock absorber.
