Multiple Targets Optimized Design of Roadheader Gyration Platform Bolt-set based on PSO

  • 摘要: 为提高掘进机的动态可靠性,建立其刚柔耦合虚拟样机模型,基于破岩理论,结合实际工况,利用项目组开发的"纵轴式掘进机截割头辅助设计及载荷计算软件"获得了掘进机的载荷文件,通过ADAMS仿真得到了回转台的应力云图,基于可靠性理论构造了疲劳寿命-可靠度隶属函数,利用NSOFT软件对回转台进行疲劳寿命可靠性分析。以螺栓组的可靠度作为训练样本,利用粒子群算法(PSO)对回转台进行优化设计,得到了最优的回转台螺栓组参数。结果表明,优化后的回转台最大应力值降低了31.669%,最小疲劳寿命由1.706×103提高至2.487 4×106次,满足设计要求。
