摘要: 针对现行热处理标准中长管形状系数准确性问题,采用ABAQUS模拟软件提供的Heat Transfer分析模块,统一采用环境辐射传热方式,建立了圆棒直径Ø20~Ø40 mm共21条模拟升温曲线组成的标准样库。利用模拟仿真及数据分析技术,提出了“等效圆棒直径条件厚度对比法”,经过模拟计算得到:短管形状系数为2,长管形状系数为2+2R/R

Abstract: For the problem of long tubular shape coefficient in the current heat treatment standard, a standard sample library consisting of 21 simulated temperature curves with Ø20-Ø40 mm diameter of the rod was established by using the Heat Transfer analysis module provided by ABAQUS simulation software and by uniform adopting environmental radiation heat transfer. Using simulation and data analysis technology, the “thickness comparison method under equivalent circular rod diameter condition” is proposed. The results show that the short tube shape coefficient is 2, and the long tube shape coefficient is 2+2Rinside/Routside.
