摘　　要：借助Ansys有限元分析软件,对法兰加热过程进行了有限元模拟,研究了加热过程中的热边界条件,分析了温度场和应变场的分布及其变化。对比不开孔和开孔的法兰在升温过程的温度分布情况,结果表明它们的温度分布场不同。分析结果对于掌握法兰结构的加热过程温度变化、分析残余应力具有实际指导意义。The temperature field of flange during heating process is analyzed by Ansys software.The heat transfer boundary condition is studied,and the distribution and change of temperature field in the heating process are analyzed.The temperature distributions of flanges with and without circles are compared.The result shows that the temperature distributions and stress distributions are different,which provides practical reference for the heating control and the analysis of the residual stress in flanges.
