高熔点钢板电阻点焊电极传热特性数值模拟与分析
Numerical Simulation and Analysis of Heat Transfer Characteristics in Electrode of Spot Welding for High Melting Steel
摘要
Abstract
In this paper ,numerical simulation , based on volume controlled method ,is used to study and analyze the heat transfer characteristics in the electrode of spot welding for 22MnB5 steel.The study focu-ses on the field distribution of electrode temperature and cooling water .It also explores the factors influ-encing heat dissipation capability of electrode , such as the concave angle on the bottom surface of elec-trode cooling cavity , the distance between the cooling water pipe and the bottom surface , and the end-face corner cut of cooling water pipe , upon which electrode structure is optimized .The results show that , in normal operation,the cooling capacity of the optimized eletrode has greatly improved and the total cool-ing time is 2 s less than that of the non-optimized one .关键词
