摘要/Abstract

摘要： 针对矿用电动轮自卸车轮边减速器存在自重大、效率低的问题,在满足平稳运行的前提下,对轮边减速器传动系统进行了多目标优化设计.采用具有遗传思想的粒子群(GA-PSO)杂交算法,将行星轮系的体积和传动效率作为优化目标,考虑装配等8种约束条件对目标函数进行约束,建立数学模型并且进行求解.通过对比分析优化前、后的模型可以发现,优化后轮边减速器的传动效率提高了0.79％,体积减小了11.36%.根据实际工况设置载荷谱并对优化后各齿轮的寿命进行分析,结果表明,二级太阳轮的最大损伤比为9.63%,总寿命可达756 400小时,其他齿轮的寿命均满足设计要求.

Abstract: Aiming at the problems of heavy weight and low efficiency in the wheel reducer of the mining electric wheel dump truck, the multi-objective optimization design of the wheel reducer drive system is carried out on the premise of satisfying the smooth operation of the wheel reducer. The particle swarm optimization (GA-PSO) hybrid algorithm with the genetic idea is adopted. The volume and transmission efficiency of planetary gear trains are taken as the optimization objectives, which is constrained by 8 constraints such as assembly, and the mathematical model is established and solved accordingly. By comparing and analyzing the original model and the optimized model, it is shown that the transmission efficiency of the wheel reducer after optimization is increased by 0.79% and its volume is reduced by 11.36%. The load spectrum is set according to the actual working conditions, and the life of each gear after optimization is analyzed. The results show that the damage ratio of the secondary sun gear is the largest which is 9.63%, with a total service life reaching 756 400 h. The service life of other gears meets the design requirements.
