摘　　要：为了减小服务卫星抓捕机构上的导向机构对目标卫星发动机喷管的撞击力,对导向机构有无阻尼对目标卫星撞击力影响进行了分析;根据UG模型,结合adams软件,对运动的导向机构在不同速度有无阻尼的情况下,进行了动力学分析。通过上述两种速度有无阻尼器的情况对比分析可以看出,有阻尼器能够有效降低导向瓣与喷管间的接触力,接触力大约减小10%撞击力有所减小,并且,目标卫星撞击后的偏转位移量减小约15%目标卫星被撞击后偏转位移量有所减小。In order to guide service mechanism to reduce the impact force of the satellite capture mechanism on the target satellite engine nozzle,the guide mechanism has no damping has carried on the analysis to the target satellite impact force;according to the UG model,combined with ADAMS software,the guiding mechanism of the movement has no damping in different speeds,the dynamic analysis.Through the above two kind of speed is a contrastive analysis of the damper can be seen,a damper can effectively reduce the contact force between the valve and the guide nozzle,the contact force is reduced about 10%impact force decreased,and the deflection displacement of the target satellite after the impact is reduced by about 15%after being hit the target satellite deflexion displacement decreases.
