Abstract
This paper presents a simulation analysis of the Roll-Over Protection Structure (ROPS) for a crawler pipelayer’s cab, focusing on the impact of weld seams on performance. Comparative simulations with and without weld seams were conducted using Ansys Workbench. The results indicate that the weld presence can enhance lateral energy absorption by up to 731.21 J, with an average increase of 4.405%. The study also utilized the XGBoost algorithm to predict weld fractures and applied birth-death element technology to manage them effectively. The findings provide new insights into the design of ROPS for crawler pipelayers, highlighting the importance of considering weld impacts in simulation analysis and providing a theoretical basis for further structural optimization.
