Prediction and analysis of axial performance of high-strength steel roller pressed crossbeams
In response to the issue of the impact of laser welding on the accuracy of axial static pressure simulation of day shaped beams,the characteristics of laser welds and methods to improve the accuracy of CAE simulation analysis were studied.This paper investigates the mechanical properties of roller pressed beam materials and laser weld material properties,explores the reasons for significant errors in axial static pressure test and simulation analysis of beams,and uses Hyperworks-CAE simulation analysis software to analyze the axial static pressure test of beams.The forms of beam collapse,weld failure,and axial cross-sectional force values under simulation conditions were extracted.By adjusting the material characteristics of laser welding seams and achieving high-precision benchmarking between experiments and CAE simulation,this paper proposes a CAE simulation analysis and prediction test method.The predictions made using this simulation method are consistent with the experimental results.
