【摘要】 通过对电阻点焊加压机构的受力分析,建立了点焊过程的动力学方程,并应用Matlab软件的Simulink工具箱进行了仿真分析。仿真结果与实测的电极位移曲线对比分析表明,建立的动力学方程和仿真模型可以表征点焊加压过程,这种方法为电阻点焊机的设计和点焊热—机联合作用过程的理论分析提供了一种新思路。更多还原

【Abstract】 Through dynamic analysis to the pressure machanism of resistant spot welding(RSW),the kinetic equation was established for RSW progress.At the same time,simulation analysis was carried out by means of the Simulink toolbox of matlab software.Compared the simulation input with result measured of electrode displacement curve,this is shown that the pressure process of spot welding can be characterized by the kinetic equation and the simulation model.The method provides a new train of thought for the design of RSW machine and theoretical analysis of heat-pressure combined process in spot welding.更多还原
