【摘要】 本文以WS-005型试验用单斗挖掘机为基型,通过对矿石挖掘过程参数的测试和数据处理,求出了正铲挖掘轨迹的拟合曲线,进一步导出了最佳切削角;作为特例,还推导了等后角挖掘轨迹方程;分析了挖掘过程各参数对挖掘阻力的影响。在此基础上求得了线性和幂函数两种数学模型下的挖掘阻力方程。更多还原

【Abstract】 With model WS-005 test excavator as basic model, through measuremnt and data processing of parameters during ore excavating process, curve fit of face excavation profile was performed and optimum cutting angle was further determined. As particular instance, equations for constant back angle excavation profile were derived; impacts of various parameters on cutting resistance were analysed. Excavation equations for both linear and exponential mathematic models are determined based upon above studies更多还原
