摘要
针对液压支架连杆制造批量大、质量不好控制的问题,引进连杆焊接机器人,在分析焊接工艺参数的基础上,应用有限元软件MSC-Marc模拟了连杆盖板单边V形坡口多层多道焊,获得了三维多道焊接温度场和残余应力场,并对结果进行了分析,对改进焊接工艺有一定的指导意义。
According to hydraulic support connecting rod manufacturing batch big, bad quality control problem, the introduction of connecting rod welding robot, on the basis of the analysis of welding process parameters, the application of finite element software MSC-Marc to simulate the unilateral connecting rod cover board V groove multi-layer welding, muhichannel acquired three-dimensional muhichannel welding temperature field and residual stress field, and the results are analyzed, to improve the welding process has certain guiding significance.
