摘要
以EBZ-300型纵轴式掘进机回转机构为研究对象,通过三维建模和有限元分析方法,对煤矿掘进机回转机构运行性能进行整体分析,确定当前该回转台结构在运行过程中,存在着铰接处应力值高度集中的问题。对此,采用受力分析与遗传算法优化相结合的方式,对该煤矿掘进机的回转结构进行优化,重点则是以作用力最小为优化目标,通过调整力臂寻找最优值,最终通过对铰接点位置寻优的方式进行优化。相对而言,优化后的回转机构应力值显著降低,表明此次研究在理论上较为可行。
Taking the EBZ-300 longitudinal roadheader slewing mechanism as the research object,through three-dimensional modelling and finite element analysis method,the overall analysis of coal mine roadheader slewing mechanism operation performance is carried out,and it is determined that the current slewing table structure in the process of operation,there exists the problem that the stress value at the articulation is highly concentrated.In this regard,the combination of force analysis and genetic algorithm optimisation is used to optimise the slewing structure of the coal mine roadheader,with the focus on the optimisation objective of minimising the force,searching for the optimal value by adjusting the force arm,and ultimately optimising the position of the articulation point by optimising the position of the articulation point.Comparatively speaking,the stress value of the optimised slewing mechanism is significantly reduced,which indicates that this study is theoretically feasible.
