【摘要】 爬行式气电立焊机器人的磁吸附机构距离熔池较近,而且采用了磁悬浮铜滑块设计,考虑到温度对铁磁性的影响,研发中需要了解焊接温度场的分布状况。该文以Rykalin公式为基础,构建了气电立焊的温度场模型,采用Matlab7.0.4软件进行了数值计算和仿真,得到了焊接过程中的温度分布。研究表明,温度场对于爬行式气电立焊机器人的磁吸附机构基本没有影响,但是会直接影响到吸附铜滑块的设计,因此在计算悬浮磁块吸力的时候需要考虑温度系数。气电立焊温度场模型的建立为爬行式气电立焊机器人的磁吸附机构和磁悬浮铜滑块的设计提供了重要依据。更多还原

【Abstract】 Crawl-type electrogas welding robots use maglev copper sliders with the magnetic attraction part close to the weld pool.Therefore,the thermal effects must be analyzed to determine the temperature distribution around the electrogas welding equipment.The Rykalin equation was used to model the electrogas welding temperature field with the calculations done in Matlab 7.0.4.The results show that the temperature field during electrogas welding will not influence the magnetic attraction,but should be considered in the design of the maglev copper slider,so temperature coefficients must be used in the analysis of the maglev attraction force.The calculated temperature fields provide a basis for the design of the magnetic attraction part and the maglev copper slider in crawl-type electrogas welding robots.更多还原
