Abstract The paper describes an analytical and experimental framework which investigates performance of electrically-driven ground vehicles powered by battery packs, with the objective of providing simple indications for preliminary sizing of rovers designed for mission on the surface of extraterrestrial bodies. For this class of missions, power is at a premium, and energy-efficient locomotion is clearly a critical issue. An analytical model for the estimate of cruise distance is derived and mobility performance is thus analyzed as a function of cruise speed, relevant vehicle parameters, soil mechanical properties, and atmospheric data. Results are then validated by numerical simulations and an experimental campaign for an Earth-based rover.

电动地外漫游车性能分析及选型指南

摘要 本文描述了一个分析和实验框架，该框架研究由电池组驱动的电动地面车辆的性能，目的是为设计用于地外天体表面任务的漫游车的初步尺寸提供简单的指示。对于此类任务，动力非常宝贵，而节能运动显然是一个关键问题。推导出用于估计巡航距离的分析模型，因此将机动性能作为巡航速度、相关车辆参数、土壤机械特性和大气数据的函数进行分析。然后通过数值模拟和地球漫游车的实验活动来验证结果。
