摘要
设计了一种航天用分步预紧连接装置。介绍了装置结构,分析了工作原理,进行了钢球受力计算。对波簧进行有限元分析,进而实现参数优化。通过应用这一装置,可以满足深空探测任务土壤转运至返回器过程中分步预紧的要求。
A step-by-step preload connection device for aerospace was designed.The structure of the device was introduced,the working principle was analyzed,and the force calculation of the steel ball was carried out.The finite element analysis of the wave spring was carried out for parameter optimization.By applying this device,the step-by-step preload requirement of soil transferred to the returner for deep space exploration mission can be met.
