摘要
针对电铲工作装置驱动力设计问题,使用EDEM计算挖掘阻力,计算结果与理论值一致。在Adams中建立电铲工作装置动力学模型,利用Simulink生成接近实际的提升和推压位移曲线,并将EDEM输出的挖掘阻力转化为挖掘阻力曲线,实现Adams-Simulink联合仿真。挖掘轨迹、驱动力仿真结果与理论计算结果一致。该方法可克服传统计算只取个别位姿的不足,为后续设计提供依据。
As to the driving force design for the power shovel manipulator,the digging resistance is calculated by EDEM,and the results agree well with the theoretical values.The dynamic model of the power shovel manipulator is built in Adams.The displacement curves of hoisting and crowding are obtained by Simulink,which is closed to the real process.The digging resistances outputted by EDEM are converted to a digging resistance curve.The co-simulation of Adams-Simulink is achieved.The simulation results of digging trace and driving force are consistent with the theoretical calculation values.This method can overcome the disadvantage of traditional calculation which only takes individual postures,and it can provide a basis for subsequent design.
