    Abstract
  • In order to design optimum shock absorber for vehicle, its optimal damping coefficients were studied according to the optimization damping ratio of suspension, a mathematic model of its velocity characteristic was built, an optimal design method of its valves parameters was put forward, its performance and whole vehicle vibration tests were carried out, and its performances were compared with that of original shock absorber. Computation result shows that the maximum warp between testing values and optimal requiring values is 9%, the transfer function values of whole vehicle vibration with designed shock absorbers are lower than that with original shock absorbers in the scope of low frequency, the resonance hereabout 13 Hz is depressed, so the model and method are feasible.
