Abstract
The semi-active damping control system with continuously variable shock absorber is widely used to improve the vehicle dynamic characteristics such as ride comfort and driving safety. To achieve better vehicle performance, the continuously variable shock absorber must have a fast response time with wide range of damping force variation. In this paper, the analytic model is developed to estimate the effect of various parameters on dynamic behavior of the variable shock absorber, such as electromagnetic properties of solenoid, vibration of moving valve body and pressure prevailing time at damper stage due to compressibility of oil and container. By analyzing the derived model and carrying out the parametric studies, the response time of the shock absorber was reduced and it was verified by rig test.
