摘要
地面力学是研究越野行驶中机器与地面相互作用的一门力学学科,包括对机器通过性的预测和评价,行走机构的优化设计以及对地面可行驶性的预测判断等几个方面.首先简介地面力学的研究方法、试验仪器和设备以及主要的成果和结论,其中包括在这些方面的最新研究进展情况.之后重点介绍行星探测领域中所开展的地面力学研究,主要从行星探测器设计阶段对地面力学理论和方法的应用、行星模拟土壤研制和力学特性研究、行星就位土壤力学参数测量等几个方面进行了综述.最后对这一领域今后的研究方向进行了探讨.
Terramechanics concerns studies on the interaction between vehicles and rough terrain in off-road locomotion. The main topics include prediction of vehicle mobility performance, optimum design of mobility systems and soil trafficability evaluation. In this paper, the methodology, test equipment and main results of terramechanics are reviewed, and the recent progress is discussed. The paper focuses on the applications of terramechanics theory in planetary exploration, including the design, validation of planetary rover, development and characterization of simulated soil and in situ mechanical parameter measurement of planetary soil. The possible future directions of this field are also discussed.
