摘要

本研究设计了一种新型双旋转肩（DRS）工具，可在搅拌摩擦焊（FSW）过程中产生预热效果并促进肩部影响区域的材料流动。使用 DRS 工具和传统工具对 AA 6061 铝合金在 FSW 过程中的温度场、应变场和材料流动进行了数值模拟比较研究。根据两种情况下的实际温度场对模型进行了验证。此外，还对两种接头的宏观形态和机械性能进行了研究。结果表明，使用 DRS 工具进行 FSW 时的模拟温度场与实际温度场具有良好的相关性。DRS 工具确实会导致不同的宏观形貌，但对机械性能几乎没有影响。

Simulation and Experimental Analysis of Double Rotating Shoulder Friction Stir Welding

In this work, a new Double Rotating Shoulder (DRS) tool is designed to create a preheating effect and promote material flow in the shoulder-affected area during friction stir welding (FSW). A comparative study of the temperature field, strain field and material flow of AA 6061 aluminium alloy during FSW using a DRS tool and a conventional tool was carried out using numerical simulation. The model was verified according to the actual temperature field in both cases. Further, the macroscopic morphology and mechanical properties of both joints were investigated. The results showed that the simulated temperature field during FSW using a DRS tool has a good correlation with the actual temperature field. The DRS tool does lead to different macroscopic profiles but has almost no impact on mechanical properties.
