Simulation Study on the Semi-Active Suspension System with Proportional Relief Valve
摘要
Abstract
The influences of the orifice diameter and the pressure regulating error of proportional relief valve on the performance of semi-active damper were analyzed using the established model of semi-active damper with proportional relief valve, the skyhook damping semi-active controller system model and the dynamic model of vehicle system. The results show that the semi-active suspension system with proportional relief valve can effectively reduce carbody vibration, and with the increase of vehicle speed, the reduction of carbody vibration is much more obvious. Based on the established dynamic model vehicle system and corresponding to each speed level of vehicle, the ride comfort index of vehicle reaches a comprehensively optimal value when the damping coefficient of skyhook is 100 kN ? S ? M-1. Increasing the orifice diameter will slow the response of semi-active damper and minify its equivalent damping, which will lead to the undesirable traceability of the semi-active damper force to the damping force expected by controller. The vibration energy of vehicle will be greater when the vibration frequency is around 1 Hz. The pressure regulating error coefficient only has slight influence on the lateral vibration of the carbody in the range of high frequency.关键词
