摘要
支重轮作为挖掘机底盘的重要组成部分,主要起承担机身重量的作用,其可靠性直接影响着行走系统的可靠性。针对某38 t级挖掘机支重轮,采用ANSYS有限元分析软件对其进行应力及应变分析,据此找到受力薄弱处,提出采用加长轴套的结构优化措施。通过对比优化前后的支重轮有限元分析结果可知,优化后的支重轮最大变形量减少约5.7%,最大应力降低约10.6%;优化后的轴套最大变形量减少约6%,最大应力降低约22.8%。
As an important part of the excavator undercarriage,the track roller mainly plays a role of bearing the weight of the machine body,and its reliability directly affects the reliability of the travelling system.For the track roller of a 38-t excavator,ANSYS finite element analysis software is used to analyze its stress and strain to identify the weak point of stress,and a structural optimization measure of using a longer sleeve is proposed.By comparing the finite element analysis results of the track roller before and after optimization,it can be seen that the maximum deformation of the optimized track roller is reduced by about 5.7%with a reduction in the maximum stress by about 10.6%,while the maximum deformation of the optimized sleeve is reduced by about 6%with a reduction in the maximum stress by about 22.8%.
