建立准确、实用的月球着陆探测器动力学模型,是制导、导航和控制系统方案设计中的首要工作,文中月球软着陆探测器的推进剂贮箱采用横向对称分散布局的形式,并分析了布局方式对液体推进剂晃动的影响;将贮箱内液体考虑一阶弹簧质量模型,应用虚功率原理建立包含液体推进剂晃动的月球软着陆探测器从动力下降段至最终着陆段的动力学模型,并对动力学下降段进行了数值仿真,仿真结果可为月球软着陆探测器控制系统设计提供理论参考.

The propellant tank of the Lunar soft-landing explorer adopts lateral symmetry dispersible layout, and the effects of the layout on the liquid propellant sloshing were analyzed. Liquid in the tank was considered as the first-order spring mass model, and the dynamics model of Lunar soft-landing explorer including propellant shake was established by using virtual power principle and the dynamics model was applicable from the dynamics descending stage to the landing stage. Finally, the dynamics simulation of descending stage was made and the simulation results can provide theory reference for explorer control system design.
