摘要: 建立了果园运输机牵引系统虚拟样机,研究了牵引系统动力学特性及钢丝绳受力特点。结果表明:相对于梯形速度曲线,S形速度曲线使载物滑车振幅明显降低、钢绳四关键点平均峰值力及受力均值分别减小了9.2 %和12.7 %。牵引系统动力学计算与仿真值平均相对误差为4.8 %,试验与仿真值平均相对误差为4.02 %,证明仿真数据可靠。该文为山地果园牵引式双轨运输机的整机设计及速度控制系统优化提供依据。

Abstract: After the traction system virtual prototype model of mountain orchard transport was established, virtual simulation test was done to get the force of wire rope and the dynamic characteristics. Compared with trapezoidal velocity, under S type velocity curve, vehicle vibration amplitude was decreased obviously in each stage, average maximum force and average force of four key points was respectively decreased by 9.2% and 12.7%. Average relative error between kinetic parameters calculation and simulation values was 4.8%. Average relative error between test and simulation values was 4.02 %. This research results have provided a simulation platform and reference to whole design and optimist the velocity control system of this machine.
