摩擦焊是一种质量好、自动化程度高的固态焊接技术。它已广泛应用于许多工业领域，特别是在汽车和航空航天工业中。惯性摩擦焊由于具有工艺参数少、自动化程度高的特点，在很多领域得到了广泛的应用。本文开发了二维热机械有限元模型来模拟惯性焊接过程。在该模型中，考虑了材料的热性能和机械性能的温度依赖性。采用有限元软件MSC.Marc对惯性摩擦焊接过程中的温度场、应力场和应变场进行计算。对GH4169高温合金惯性摩擦焊接过程中的瞬态温度场和变形进行了预测。采用热电偶测量惯性摩擦焊接过程中的温度场。计算得到的温度场与实验结果吻合较好。
Friction welding is a solid state welding technology with good quality and high automation. It has been widely used in many industry fields especially in automobile and aerospace industry. Because of the characters of less process parameters and high automation, inertia friction welding is popular in many fields. In this paper, a 2-D thermo-mechanical FEM model was developed to simulate inertia welding process. In this model, the temperature dependency of the thermal and mechanical properties of material was considered. The finite-element software MSC.Marc was used to calculate the temperature field, stress field and strain field during inertia friction welding process. The transient temperature field and the deformation of GH4169 superalloy during inertia friction welding process were predicted. The temperature filed during inertia friction welding process was measured by means of thermocouples. The calculated temperature filed is in good agreement with the experimental result.
