摘要
针对掘进机中回转台在作业过程中出现的结构失效风险,结合ZBZ160型矿用掘进机中回转台的结构特点,利用ABAQUS软件,分析回转台在作业过程中的结构性能,发现回转台前端与升降油缸铰接处存在较大的应力集中及位移变形,是整个结构的薄弱部位,这与回转台实际作业时此部位极容易出现故障失效现象相吻合。为此,从结构尺寸、材料属性等方面提出了对回转台的优化改进措施,以提升回转台铰接耳处的结构强度,降低油缸对回转台结构的作用力,减小甚至消灭回转台结构变形,从而提高回转台的结构强度及作业安全性。
In view of the structural failure risk of rotary table in roadheading machine,combined with the structural characteristics of rotary table in ZBZ160 mining roadheading machine,the structural performance of rotary table during operation is analyzed by ABAQUS software,and it is found that there are large stress concentration and displacement deformation at the articulation of front end of rotary table and lifting cylinder,which is the weak part of the whole structure,which is consistent with the actual operation of rotary table.This is consistent with the actual operation of the rotary table when this part is very easy to failure phenomenon.In this regard,the improvement measures for the rotary table are proposed in terms of structural dimensions and material properties,in order to improve the structural strength of the rotary table at the articulated lug,reduce the force of the cylinder on the rotary table structure,reduce or even eliminate the structural deformation of the rotary table,so as to improve the structural strength and operational safety of the rotary table.
