Analysis on temperature field and residual stress field of ultrasonic assisted friction stir welding

摘要

    摘要
  • 摘要: 超声辅助搅拌摩擦焊是一项在搅拌摩擦焊的搅拌头上添加轴向高频振动的新技术. 以6 mm厚7075铝合金材料为研究对象，建立了超声辅助搅拌摩擦焊与普通搅拌摩擦焊接的热源模型，通过ANSYS软件研究了轴向振动对焊接过程温度场以及焊后残余应力的影响规律. 结果表明，轴向振动的添加能够增大热输入量，提高焊接峰值温度且降低焊缝残余应力；在相同转速及焊接速度下，当振动频率一定时，焊接峰值温度和焊后残余应力随着振动幅值的增加而增大；当振动幅值一定时，随着振动频率的增大，焊接峰值温度及焊后残余应力也相应增加.
    Abstract: Ultrasonic assisted friction stir welding (UAFSW) is a new technology of adding axial high frequency vibration on the mixing head of friction stir welding (FSW). The 7075 aluminum alloy with 6 mm thickness was used as the research object, and the heat source model of UAFSW and FSW was established, the influence of axial vibration on the temperature field and residual stress was investigated by ANSYS software. The results show that the addition of axial vibration can increase the heat input, increase the peak welding temperature and reduce the residual stress of the weld. When the vibration frequency is constant, the peak welding temperature and residual stress increase with the increase of vibration amplitude at the same rotating speed and welding speed.When the vibration amplitude is constant, with the increase of vibration frequency, the welding peak temperature and residual stress also increase correspondingly.
