摘要

高速搅拌摩擦焊(HSFSW)的界面滑移状态很难确定,也无法获得精确的边界条件。本文首先研究了速度和温度对界面滑移状态的影响,并建立了一个新的滑移系数方程。然后,利用该方程修改了速度边界条件,改进了 HSFSW 的数值计算方法。建立了 HSFSW 的数值模型,并通过实验数据进行了验证。最后,阐述了横移速度和旋转速度对 HSFSW 温度和空隙缺陷的影响,并确定了适用的工艺参数范围。具体而言,在转速为 6000 rpm、横移速度为 1000 mm/min 和 2000 mm/min 时观察到了空隙缺陷,而在横移速度为 3000 mm/min 和转速为 7000 rpm 时则出现了表面剥落。这项研究确定了铝合金 HSFSW 的最佳参数范围,为未来的工业应用提供了宝贵的指导。

An improved numerical model of high-speed friction stir welding using a new tool-workpiece slip ratio

The interface slip state of high-speed friction stir welding (HSFSW) is challenging to determine, and accurate boundary conditions cannot be obtained. First, this paper studies the effects of velocity and temperature on the interface slip state, and establishes a new slip coefficient equation. Then, this equation was used to modify the velocity boundary conditions and improve the numerical calculation method of HSFSW. A numerical model of HSFSW was established and validated through experimental data. Finally, the effects of traverse speed and rotational speed on the temperature and void defects of HSFSW were elaborated, and the applicable process parameter range was determined. Specifically, void defects were observed at a rotational speed of 6000 rpm with traverse speeds of 1000 mm/min and 2000 mm/min, while surface peeling occurred at a traverse speed of 3000 mm/min with a rotational speed of 7000 rpm. This study establishes the optimal parameter range for aluminum alloy HSFSW, providing valuable guidance for future industrial applications.
