弧焊熔滴过渡混沌的若干问题探讨

探讨指出现今弧焊熔滴过渡数学模型中存在只关注于单个周期内不同过渡阶段熔滴的特征行为,而忽略过渡周期之间关联特性的不足。通过叙述相关的混沌基本概念,以及结合滴水龙头混沌的相关运动规律,提出建立弧焊混沌数学模型在本质上能更真实地反映熔滴过渡过程。介绍了滴状过渡和短路过渡中混沌研究现状,指出目前急需解决的问题是建立精确的混沌数学模型。展望了弧焊在不同混沌控制目标中的应用前景。

Discussion on Several Problems for Chaotic Metal Transfer in Arc Welding

The drawback in mathematic model of metal transfer was analyzed,and it was the attention being only paid to droplet movement of different stages in a single transfer period.According to the related chaos theory and the related chaotic movement characteristics in dripping faucet,a establishing chaotic model can reflect better in essence the metal transfer is put forward.The progresses of chaotic research on drop transfer and short circuiting transfer were introduced and the problem was pointed out that an ac...
