基于辐射测温的弧焊机器人GMAW动态过程辨识

Identification of GMAW dynamic process of arc welding robot based on radiation temperature measurement

研究弧焊机器人GMAW(Gas Metal Arc Welding,熔化极气体弧焊)动态过程,采用比色测温仪对温度场特定点温度进行采集,采用面积法对送丝速度和测温点温度之间的模型进行了辨识.仿真结果表明,该模型准确地反映了输入输出的关系,仿真数据与实验数据的均方差仅为30/0.

The dynamic process of arc - welding robot GMAW is researched. The stationary location temperature is measured by colourimetric temperature measurement device. The model between weld feed speed and temperature is identified by the way of area method. The simulation result shows that the control model reflects the relationship between input and output and the error between simulation date and test date is only 3%.
