将挖掘机工作装置视为一个整体,建立了工作装置整体优化设计数学模型.以挖掘机的挖掘力为优化目标函数,以工作装置各铰点位置的几何参数为优化设计变量,基于遗传算法进行编程,并以某挖掘机工作装置为例进行优化求解.计算表明:在保证挖掘机工作区间在一个合理范围内的前提下,只需将工作装置铰点位置做少许调整,就可以使挖掘机的挖掘性能得到明显改善,铲斗和斗杆的最大挖掘力分别提高1%和5%.采用遗传算法可以快捷而有效地对挖掘机工作装置铰点位置进行优化设计,是对挖掘机性能进行优化设计的一种有效方法.
Taking the excavator working device as a whole, the mathematical model of the overall optimization design of the working device is established. Taking the excavating force of the excavator as the optimization objective function, taking the geometrical parameters of each hinge position of the working device as the optimization design variables and based on the genetic algorithm Programming and an excavator working device as an example to optimize solution.Calculation shows that: in ensuring the excavator working area within a reasonable range under the premise of only the hinge position of the working device to make a little adjustment, you can make the excavator The excavation performance of the excavator is obviously improved, and the maximum digging force of the bucket and the stick is increased by 1% and 5% respectively.Using genetic algorithm to optimize the design of the hinge point of excavator working device quickly and effectively, An effective way to optimize design.
