Abstract

Based on the working principle, the internal configuration, and the valve system behavior of the shock absorber, the equation for annular laminar deformation under a uniform load is deduced by using a deflection differential equation for throttle slice and boundary condition, according to hydrodynamics gap flow, nozzle flow and small orifice throttle theory, mathematical model of working procedure is established. The Matlab software was used to simulate a detailed model of an automotive shock absorber, the calculated results agree well with the test data. In particular, the effects and sensitivity degrees of the suction valve and intake valve on the shock absorber damping were analyzed by the model, and the obtained results provide a reference for the shock absorber design and performance prediction.
