中文摘要: 针对目前尚未有精确描述埋弧焊系统的数学模型而难以达到理想控制目标的现状, 对埋弧自动焊系统按照机理建模的方法建立数学模型, 分别建立了焊丝电压降子模型、熔滴电压降子模型和电弧压降模型三个子模型, 作为埋弧焊系统中控制电弧的理论依据, 并进一步根据所建立的模型提出了相应的变速送丝控制方案, 经过控制系统的仿真验证了控制方案可以维持埋弧焊过程中送丝速度变化和焊接电弧之间的稳定性.

中文关键词: 埋弧自动焊系统数学建模压降子模型变速送丝控制方案稳定性

Abstract:In allusion to the current situation that there is not yet mathematic model of describing the submerged arc welding system accurately, the mathematical model is established on the basis of mechanism modeling. Welding wire voltage drop son model, molten drop voltage son model and electric arc voltage drop son moder are established, which are regarded as the theoretical basis of the theoretical basis of the submerged arc welding system to control electric arc. And the corresponding variable speed wire control scheme is proposed according to the established model. By the control system simulation, it proves that the control scheme can maintain the stability between the wire feeding speed change and welding electric arc in the submerged arc welding process.

keywords: automatic submerged arc welding system mathematical modeling voltage drop son moder variable speed wire control scheme stability
