通过对月球车和火星车的跟踪调研,重点介绍了俄罗斯所承担的欧洲空间局“火星快车”项目中火星车自行底盘概念的设计思想和具体实施情况.结合火星表面的复杂环境,研制方探讨了几种底盘结构设计方案,通过对比分析确立了6×6×4+4Ⅲ方案为优化方案；根据该优化方案研制的比例模型样机通过行走试验验证,结果表明自行底盘概念设计思想正确,有助于提高行星车在复杂地形中的运动能力、稳定性和可靠性.最后针对我国深空探测项目实施的需求,提出了拟开展工作建议.%This paper describes the conceptual design of the self propelling chassis developed by Russia for the ESA project ExoMars. In the context of the complex environment on the surface of the Mars, several design plans of the Mars probe chassis are discussed, among which the optimized plan of 6×6×4+4 Ⅲ is identified, that means four steering drives and four stepped-driven wheels-stepping device and balanced suspension. The scale model prototype developed according to the optimized plan was tested in the test field. The results show that the conceptual design of the self propelling chassis is correct, and can increase the mobility, stability and reliability of the planet rover. In the end, some proposals are put forward in light of implementing China's deep space exploration projects.
