同时测量搅拌摩擦焊过程中的工具扭矩、横向力和轴向力，对于理解搅拌摩擦焊过程机理和优化工艺参数具有重要意义。与传统的使用称重传感器或旋转元件测力计的测量方法不同，本研究采用一种间接但经济的方法，通过监测搅拌摩擦焊机床内伺服电机和主轴三相交流感应电机的输出转矩，同时测量横向力、轴向力和刀具转矩。在不同的焊接条件下，测定了横向力、轴向力和工具扭矩的值，并对影响因素进行了分析。对AA 2024-T4铝合金在不同搅拌头转速和焊接速度组合下的搅拌摩擦焊试验结果进行了分析，为优化工艺提供了依据。
Simultaneous measurement of the tool torque, traverse force and axial force during friction stir welding process is of great significance to the understanding of the underlying process mechanism and the optimizing of the process parameters. Different from the traditional measurement methods using load cell or rotating component dynamometer, an indirect but economical methodology is used in this study for the simultaneous measurement of the traverse force, axial force and tool torque by monitoring the output torques of the servo motors and main spindle three-phase AC induction motor inside the FSW machine. The values of the traverse force, axial force and tool torque are determined under different welding conditions, and the influencing factors are examined. The measured results in friction stir welding of AA2024-T4 aluminum alloys at different combinations of tool rotation speed and welding speed lay foundation for process optimization.
