Abstract Plasticine of primary colours was utilized and the hue attribute of generated secondary colour was tracked. The degree of mixing was indicated by the intensity of secondary colour. Hue component was obtained from digital images of joined plasticine cross-section by converting RGB colour-maps to HSV colour-maps. Effect of tool pin profile that included circular, hexagonal, square and triangular was examined in this context. As the number of faces on the tool pin reduces, up-till pin with four faces (square) the pin induced mixing increases and results in the elimination of joint line remnant. Material adjacent to the face was transported in lumps and experienced spinning/whirling movement. During mixing phenomenon flow velocities of constituents undergoing it tends to fluctuate. The fluctuation is significantly large for higher levels of mixing and the same was noticed for a square profile from the results of finite element simulations. The results obtained from plasticine and finite element simulations are validated using aluminium weld.

搅拌摩擦焊材料混合的橡皮泥建模

摘要 利用原色橡皮泥，跟踪生成的二次色的色调属性。混合程度由二次色的强度表示。通过将 RGB 颜色图转换为 HSV 颜色图，从连接的橡皮泥横截面的数字图像中获得色调分量。在这种情况下检查了包括圆形、六边形、方形和三角形在内的工具销轮廓的影响。随着工具销上的面数减少，具有四个面（方形）的向上直到销引起的混合增加并导致接头线残余物的消除。靠近面部的材料成团运输并经历旋转/旋转运动。在混合现象期间，经历它的成分的流速趋于波动。对于较高的混合水平，波动显着较大，并且从有限元模拟的结果中注意到方形轮廓的波动较大。使用铝焊缝验证从橡皮泥和有限元模拟中获得的结果。
