摘要
文章进行了月球车单个车轮和模拟月壤相互作用的初步研究,并将两种不同轮下分布模型得到的单轮力学性能仿真分析的结果和土槽试验结果进行了对比,从中选出合适的模型对车轮的牵引性能进行仿真计算。根据试验结果,利用动沉陷量-滑转率之间的线性关系获得了动沉陷系数,然后对不同垂直载荷、不同表面形状车轮牵引力的变化规律进行了预测,并进行了相应的试验验证。
This paper studies the interaction between the lunar rover wheel and lunar simulant. The simulation results obtained by using two different models are compared with the results of soil bin experiment, and, accordingly, one model is chosen for drawbar pull prediction. The dynamic sinkage factor is determined based on the linear relationship between the dynamic sinkage and slip. The drawbar pulls of different wheels at different loads are calculated and then validated through experiments.
