摘　　要：减振器是汽车悬架系统中的重要构成部分,能够化解由于路面颠簸传递给车身的振动冲击,从而保证汽车在驾驶过程中的操纵稳定性、安全性和舒适性。本文研发了一种可以通过手工旋转调节档位、进而改变阻尼力的新型26档位压缩阀阻尼力可调节减振器,并对该减振器的结构和工作原理、阻尼特性进行了分析,通过实际实验表明,所研发的新型26档位压缩阀阻尼力可调节减振器的实验结果与理论分析相符,示功图曲线平滑流畅、没有空程和畸变,符合国家标准要求,可以装车使用。The shock absorber is an important part of the automotive suspension system. It can resolve the vibration shock transmitted to the vehicle body due to bumps on the road surface, thereby ensuring the vehicle to keep stable ,safe and comfortable. In this paper, a new 26-position compression valve clamping force adjustable damper that can adjust the gear position by manual rotation and then change the damping force is developed. And the struc-ture, working principle and damping characteristics of the shock absorber are analyzed. The experimental research results show that new type 26-position compression valve damping force adjustable shock absorber are in line with theoretic analysis. The indicator diagram curve is smooth , with no space and distortion. The shock absorber meets the national standard requirements and can be used for loading.
