연속제어방식의 반능동형 전자제어 현가장치의 가변댐퍼 감쇠력 특성 연구 및 차량 운동성능에 미치는 효과 분석

Continuously controlled semi-active suspension system may improve ride and handling propenies. Here, as a mechanism to control the fluid flow solenoid valve mechanism is introduced and added to the basic passive damper to create damping forces of the shock absorbers. The system may produce continuously controlled damping forces related to damper velocities in efficient ways. In this paper, after constructing the valve modeling a principle creating damping forces in both solenoid valve only and combination with passive shock absorber including fluid flow is studied, and then the combined model is added to the full vehicle model to evaluate its ride and handling performance. Finally, the simulation results are compared to the vehicle models having similar suspension system.
