摘要

The study examined vibration associated with the fatigue behavior of a robotic Friction Stir Welding (FSW) system using ADAMS simulation software. Full development of an extensive model for a robot was analyzed for the structural stability and dynamic response while performing various welding operations based on a modal analysis. The study found some considerable vibration patterns in FSW operations that could cause fatigue failure in the robot component. Using the S–N curve approaches, we assessed the fatigue loading on the robot, pinpointing critical stress zones in terms of component degradation over time. Humility in Specific Damping and Vibration Isolation techniques would therefore be proposed for adoption since they have been proven effective at the alternate level in reducing vibration levels and enhancing fatigue resistance. These results could help to create a basis for which developments in robot FSW system optimization will occur as they improve the longevity of operation and the consistency of quality in the resulting welds, thereby extending the frontiers of possible futures in automated welding technology for manufacturing applications.
