摘　　要：针对载人月面移动系统在月球表面直接着陆缓冲并完成大范围移动任务的需求,设计了一种由可调姿态双横臂式金属弹簧悬架系统组成的着陆行进一体化移动系统,核心部件悬架单元由双横臂悬架构型和变阻尼摩擦式减振器组成,并由调姿组件实现悬架的构型变化和阻尼参数调整,在满足大范围平顺性移动要求的同时,能够适应大冲击着陆缓冲。根据双质量振动原理,构建了悬架参数分析模型和行驶平顺性动力学仿真模型,并开展了着陆行进仿真分析和样机着陆缓冲试验。分析和试验结果表明:载人月面移动系统设计可满足月面大冲击着陆缓冲和行驶平顺性的要求。Aiming at the requirement of the manned lunar surface mobile system to cushion the landing directly on the lunar surface and complete large-range moving tasks,an integrated landing and traveling mobile system consisting of a double-arm attitude-adjustable metal spring suspension system has been designed.The core component,suspension unit,consists of a double-arm suspension structure and a variable damping friction shock absorber,which can be adjusted by the attitude adjustment component to change the suspension configuration and damping parameters.While meeting the requirements for large-range smooth movement,it is also able to adapt to the large-impact landing buffering.Based on the principle of dual-mass vibration,a suspension parameter analysis model and a driving smoothness dynamics simulation model are constructed,and landing and driving simulations are analyzed and prototype landing buffering tests are conducted.The analysis and test results indicate that the proposed mobile system design can meet the requirements for large impact landing buffering and driving smoothness during lunar landing.
