火星车转移坡道机构展开策略分析与验证

Study and Verification on Deployment Strategy of Transfer Ramps for Mars Rover

针对有限的一套转移坡道机构,为实现火星车双向转移的需求,考虑其在轨可能出现的各种故障,在不更改原有机构的前提下,提出了一种双向可选的坡道机构自主展开策略,该策略的各项流程在坡道机构与数管软件的联试试验中得到逐一验证,各项遥测参数正常,执行时序正确,结果表明坡道机构自主展开策略执行有效、可靠性高,为火星车成功转移至火面提供有力保障。

In view of a limited kind of drawout-expanded ramps,and in order to realize two transfer channels for Mars rover,considering all kinds of faults that could be occurred in orbit,and without changing the original mechanism,a two-way optional autonomous deployment strategy is carried out in this paper,.The whole process of the strategy is verified one by one in the joint test of transfer ramps and data management software,all telemetry parameters are normal,the system sequence is executed correct,the results show that the autonomous deployment strategy of transfer ramps is effective and reliable,which provides a strong guarantee for the successful transfer of Mars rover to the surface.
