摘要 从全系统的角度建立了短路过渡GMAW系统的动态模型。在研究了短路过渡GMAW过程各物理量相互关系的基础上,在一定的条件下,以焊接回路模型为主体,进行了短路过渡GMAW过程全系统的动态模型建立,其中的液桥形状动态模型则采用了能量最小原理。在建立的动态模型基础上进行了仿真计算和误差分析,并进一步与实际的焊接过程进行了比较。 Dynamic model of a whole GMAW(gas metal arc welding) system with short circuiting transfer has been built based on relationships of all relevant physical parameters.The center of the model was the sub-model about welding circuit of short circuiting transfer.Principle of minimum energy was adopted when dynamic model of liquid bridge profile was built.Dynamic behavior of the GMAW system with short circuiting transfer was simulated with the analysis of deviations.An experimental result was used to verify the model built.
