摘　　要：月球探测用应急返回车的相关技术研究是我国未来载人登月探测的重要任务。根据应急生保和月面短距离移动需求,本文从安全舒适性、操作可靠性和工作空间出发,设计了一种立方体载人月球应急返回车,对车身构型、折展模式、驱动方式、底盘结构、悬挂转向和车轮等多个模块进行了设计优化,并进行了试制和试验。结果表明,整车能够实现自动折展,具有较高的展/折比(大于17),满足行驶、转向、越障、爬坡等移动需求。The development of an emergency return vehicle for lunar exploration is crucial for future manned Chinese lunar exploration missions.To meet the needs of emergency life insurance and short distance movement on the moon surface,this study designs a cubic emergency lunar vehicle of China(CELV)from the perspective of safety,comfort,operation reliability,and working space.Several modules,such as body configuration,folding mode,driving mode,chassis structure,suspension steering,and wheel,are designed and optimized.The results show that the vehicle can achieve a high folding ratio of more than 17,with a simplified steering structure,improved transmission efficiency,as well as greater adaptability,stability,and comfort during travel.
