Research on Simulation Analysis and Optimal Design of the Work Action Platform Structure for Intelligent Welding Robot
摘要
Abstract
Welding robots are widely used in the automotive industry.In order to ensure the stability and reliability of robot welding work,a simplified finite element model of an intelligent welding robot on the automotive welding production line is established,boundary conditions and load constraints are set,and the structural stiffness and strength of the work action platform under three typical working postures are simulated and analyzed.And the verification results are obtained under the load of 30 kg welding workpiece,and different optimization schemes are compared and simulated for the stress and deformation of the work action platform in the extreme scenario of horizontal placement of the work action platform.Optimization schemes such as the panel structure of the intelligent welding robot work action platform and the adjustment of the new fixture constraint position are proposed.Under the vertical load of 1 235 N,the maximum stress is significantly reduced to 4.31 MPa,which is 40.47%lower than the original scheme,and the maximum deformation is reduced to 0.041 mm,which is 66.39%lower than the original scheme,the results show the stiffness greatly improved and the deformation of the work action platform significantly reduced after optimization,thereby promoting intelligent welding robots to complete automotive welding processes more reliably and with higher quality.关键词
