摘要
在现场试验的基础上,通过机构运动学理论推导出的基于速度参数的挖掘机轨迹方程,结合采矿工艺流程,确定了挖掘边界条件。对主要挖掘循环过程进行优化。对挖掘过程速度参数建立多目标函数,采用全局优化中的Pointer算法,基于Isight优化设计平台进行优化。利用虚拟样机仿真验证优化结果的可行性。确定出合理的速度参数,对设计有实际指导意义。
Based on the experiments, the boundary condition of digging were determined in consideration of Kinetic theory and equation of digging locus with speed parameters. The multiple object function was created for the speed parameters in digging process. The parameters were optimized by the method of Pointer on Isight software. At last, the writer made virtual prototype simulation with ADAMS and the simulation results demonstrate that the global optimization algorithm could be able to solve the mechanical excavator work optimization.
