载人月球车馈能悬架技术及其AMESim仿真分析

Energy Regenerative Suspension Technology of Manned Lunar Rover with AMESim Simulation Analysis

基于载人月球车对行驶速度、乘坐舒适性及能量储备的要求,提出一种滚珠丝杠式馈能悬架技术方案。分析了其结构、馈能原理及悬架输出力,利用AMESim软件建立了传统悬架系统和馈能悬架系统模型,在阶跃激励和正弦激励下仿真了其车身加速度和车轮动载。结果表明,馈能悬架系统的两项评价指标较传统悬架小,其平顺性和稳定性更好,能够为可靠的月面运行提供保障。

Based on the request of running speed,riding comfort and energy reserves of manned lunar rover,a ball screw regenerative suspension scheme was proposed.The structure,principle and output force of the regenerarive suspension was analyzed.A traditional suspension system model and an energy regenerative suspension system model were implemented by AMESim software,the vehicle body acceleration and wheel dynamic load were simulated under the step excitation and sinusoidal excitation.The results indicate that the two evaluation indexes of the regenerative suspension system are smaller than that of traditional passive suspension,the ride performance and stable perfrmance are better so that they can provide guarantee for the reliable operation on the moon.
