摘　　要：“天问一号”着陆巡视器着陆火星表面后,器外电缆将面临极端温度环境,针对电缆在低温转动工况下更容易发生电连接器和导线材料损坏的问题,设计了一种转动电缆极端低温环境适应性试验方法,验证转动电缆在火星低温环境下经历多次转动后,电缆组件包含电连接器、导线及辅料的结构完整性、电性能稳定性。“天问一号”探测器的在轨飞行进一步证明了该试验方法的有效性,为后续深空探测任务中电缆对复杂温度环境的适应性提供试验方法和技术支撑。The external cables of Mars landing rover faces the extreme temperature,after“Tianwen-1”Mars landing rover lands on the surface of Mars.In allusion to cables would harden at low temperature,the materials of electric couplers and wires more easily damage when rotating at low temperature,the experiment method of low temperature adaptability of rotating cables is designed,to verify the adaptability and rotating performance of cables at Mars low temperature.The experimental results have testified that the cable assembly including electric couplers,wires and auxiliary materials are structurally integrated and electrically reliable after rotating at low temperature of Mars.Furthermore,the cables of spacecraft have experienced in-orbit flight,and have further evidenced the availability of this experiment method,and provide experiment method and technical support for the adaptability of cables to complex thermal environments of subsequent deep-space exploration.
