通过方程分析法,得出了可用来布置和总结熔池搅拌强度试验的近似模拟方程。它表明τт主要决定于 q、h/d 和ρ1/ρg,而与熔池尺寸和模型比例关系不大,并且τ与 h/d 之间具有极值关系。同时,提出了可使τ的半经验式供放大或缩小应用的方法。 Through the method of equation analysis, the approximate simulation equation that can be used to arrange and summarize the test of mixing intensity of molten pool is obtained. It shows that ττ is mainly determined by q, h / d and ρ1 / ρg, but has little to do with the size and model ratio of the weld pool, and there is an extreme relationship between τ and h / d. At the same time, we propose a method that can make the semi-empirical of τ for zooming in or out.
