Numerical Simulation of the Residual Stress of the Welding Lines in the Buffer Track of the Walking Auto-Moving Retarn End
In order to reduce the residual stress of the buffer track of the walking auto-moving retarn end,a three-dimensional model of the buffer track was established with Solidworks.Four welding schemes were designed based on Ansys workbench software and Gaussian heat source model in moving heat to simulate the welding process of the buffer track.The effect of position arrangement and welding sequence of the welding lines on the residual stress of the buffer track is studied.When the welding lines are parallel and symmetrical and the welding sequence is A-C-B-D,the overall residual stress of the welding lines is minimum,which provides theoretical guidance for the optimization of the buffer track welding process of walking auto-moving retarn end and subsequent multidimensional vibration aging process.
