嫦娥三号巡视器移动分系统需适应低重力,大温差,超高真空以及带电月尘等空间及月表环境,并承载多种科学载荷进行月表巡视.阐述嫦娥三号移动分系统的任务需求,进行移动分系统原理设计,及其驱动机构,差动机构,车轮与防尘密封圈等组件的结构设计;建立移动分系统数字样机并进行静力学,动力学与热分析及优化;对移动分系统及其组件进行模拟月面环境下的爬坡,越障,脱困和防尘密封等地面模拟试验;嫦娥三号巡视器自2013年12月15日登上月面,经受2个月球昼夜的严酷月面环境考验,已行进100多米.
Chang’e III mobile monitor system needs to adapt to the low gravity, large temperature difference, ultra-high vacuum and dust on the moon and other space-time environment and lunar surface environment, and carries a variety of scientific loads for lunar surface inspection.Elaborating Chang’e III mobile subsystems mission The design of mobile subsystem principle and the structural design of its components such as drive mechanism, differential mechanism, wheel and dust seal; establish digital prototype of mobile subsystem and carry out statics, dynamics and thermal analysis and optimization; Mobile subsystems and their components to simulate ground conditions such as hill climbing, obstacle avoidance, dust-proof sealing and other ground-based simulation tests on the lunar surface. The Chang’e III was launched on the moon from December 15, 2013 and was subjected to 2 lunar Severe lunar day environment test, has traveled more than 100 meters.
