刚性轮与模拟月壤相互作用初步研究

The interaction between a rigid wheel and lunar soil simulant

  • 摘要: 文章在初步总结当前月球车轮与月面土壤相互作用研究成果的基础上,利用自主开发的仿真平台开展了刚性车轮和模拟月壤的相互作用的仿真计算,并与土槽试验结果进行了初步的对比研究。研究表明,仿真结果和试验的测量值误差在30%以内,尤其在车轮的垂直沉陷量的计算上和试验结果一致性较好,从而验证了轮-土相互作用的模型的局部合理性,但是在切向力的计算上还存在一定的误差,需要继续完善。

     

    Abstract: A simulation of the interaction between a rigid wheel and lunar soil simulant was carried out on a platform developed specially by our institute, and the simulated results were compared with those obtained by soil bin experiments. It was found that the error was within 30%, and the predicted sinkage agrees extremely well with the experiment results, and thereby to some extent the proposed wheel-soil interaction model was validated. But the shear force prediction was unsatisfactory and further effort will be needed to improve the model.
