Research on Digital Process Simulation of Welding Path for Car Body
In response to the instability problem of traditional manual welding path planning,a fitness function combining penalty values and length values is proposed in the genetic algorithm.To address the issue of low efficiency in on-site debugging,a three-dimensional model of the actual welding station is established,and a PLC control program is developed for process simulation and virtual debugging of the entire welding station,thus solving the interference phenomenon during the welding process and verifying the sequence and layout of the welding station workflow.The research results indicate that the improved welding path reduces the time by nearly 15％compared to the original manual welding path,improving the stability of the welding path.By ccorrecting the interference phenomena during the expected welding process through process simulation,setting a reasonable workflow sequence,optimizing the PLC program and virtual debugging,on-site debugging time is reduced and debugging efficiency of welding stations is improved.
