【Abstract】 A damper with tunable throttle is designed. The structure and operation principle of the damper is illustrated. The performance of the damper is analyzed and tested. The relation between damp of the damper and angle of step-electromotor is developed. It shows that the damper performs stably. The damper can meet the design request and theoretic predictions agree with the test result. If the damper is used in semi-active suspension system, a good vibration characteristic will be received, and performance of vehicle will be improved.更多还原
