为获得更准确方便的矿用自卸车前推连杆组合式举升机构优化设计方法,通过对机构的物理模型简化和引入油压波动系数,建立了总体布置空间和几何运动约束为约束条件的优化数学模型,并应用Matlab软件了仿真优化分析.结果表明:所建的优化模型对矿用自卸车前推组合式举升机构进行参数优化是可行的,在提高举升机构举升力的同时,降低了举升系数,为举升机构设计提供了一种实用、方便的优化方法.

In order to obtain a more accurate and convenient optimization design method of the front push rod assembly lifting mechanism on mining dump truck, through simplifying the mechanism of physical model and introducing into the oil pressure fluctuation coefficient, the overall layout space and the geometric constraint for the constraints of the optimization mathematical model was established, and the simulation and optimization a- nalysis was generated with the Matlab software. The results show that： the optimization model of the mine dump truck front push assembly lifting mechanism optimization was feasible, reduced the lift coefficient, and improved the lifting mechanism of lift at the same time, and provided a practical and convenient optimization method for the lifting mechanism design.
