摘　　要：使用有限元仿真软件Visual-Environment,建立T4003不锈钢振动焊接的数值模拟模型,研究不同振动参数对焊后残余应力的影响。仿真结果表明,平行于焊缝方向的最大主残余应力呈先升高后平稳再降低的“梯形”分布。垂直于焊缝方向的最大主残余应力整体呈中间高两边低的“尖塔形”对称分布。不同方向的最大主残余应力结果表明,振动焊接能有效降低T4003不锈钢的焊后残余应力,振动频率为40 Hz,振动加速度为10 m/s^(2)的最大主残余应力最小。Using finite element simulation software Visual-Environment,a numerical simulation model of T4003 stainless steel vibration welding was established to study the effect of different vibration parameters on residual stress after welding.The simulation results show that the maximum principal residual stress parallel to the weld seam direction exhibits a"trapezoidal"distribution of first increasing,then stabilizing,and then decreasing.The maximum principal residual stress perpendicular to the direction of the weld seam is symmetrically distributed in a"spire shaped"pattern with a higher center and lower sides.The results of the maximum principal residual stress in different directions indicate that vibration welding can effectively reduce the post weld residual stress of T4003 stainless steel.The maximum principal residual stress is minimized at a vibration frequency of 40 Hz and a vibration acceleration of 10 m/s^(2).
