摘　　要：针对管板接头构件的电子束钎焊特点,建立了一个三维的有限元分析模型,利用ANSYS软件进行了钎焊温度场模拟,分析了各规范参数对温度场的影响。选用设定的参数对工件进行钎焊,并用热电偶对工件表面温度进行测量,测量与模拟分析的结果有较好的一致性,证明所建立的模型是合理的。According to the property of vacuum electron beam brazing (VEBB) of a pin-to-plate joint, the finite element method with a 3-D model is used to simulate the temperature distribution of the brazed parts with software ANSYS. The influence of different process parameters on the temperature field is analyzed, and some experiments are carried out with these parameters. The surface temperature of the brazed joint is measured by a thermocouple. The measured and simulated results are compared with each other, showing good agreement, which verifies that the model established is reasonable.
