Non-linear Characteristic Simulation of Hydraulic Shock Absorbers Considering the Contact of Valves

摘要：

　　This paper presents a detailed model of a hydraulic shock absorber.The detailed structure includes in the model,such as the deflection of valve which deforms in the oil,the contact between the superposition valves et al.The FEM is used to solve the valve deflection problem.The difference between the FEM result and formula result which is acquired by Mechanical Design Handbook is analyzed.The detailed Mathematical model is simulated by MATLAB and the simulation results fit the experiment data very well.This shows that the model can be used to forecast the performance of hydraulic shock absorber when design.
