【摘要】 本文对4×2、4×4型步行轮车辆在松软地带的动力性能进行了理论分析,建立了驱动力P_q,滚动阻力P_f,牵引力P_T和行走效率η的数学模型,借助计算机分析了P_q,P_f,P_T和η随滑转率i的变化规律,并绘制了相应的关系曲线,探讨了轮脚尺寸对η的影响。更多还原

【Abstract】 In this paper, the dynamic characters of 4×2 and 4×4 walking-wheel vehicles in soft field have been analyzed theoretically. The mathematical models of Pq, Pf, PT and ηx, have been established, the changing laws of Pq, Pf, PT and ηx, with slippage have been analyzed by the means of computer and correspondent relationship curves have been drawn, and effects of the shoe’s size on ηx have been discussed.更多还原
