摘　　要：根据线性摩擦焊振动系统的简化模型,推导了焊接过程热输入数学模型,并通过热过程分析,建立了线性摩擦焊三维热分析有限元计算模型;利用有限元软件ANSYS计算获得了45钢线性摩擦焊接头温度场的分布特征,并与用金相组织法测定的接头温度场进行比较,验证了模拟结果。According to the simplified model of the linear friction welding （LFW） vibration system, the mathematic model of the thermal source during the welding process was deduced. Based on the analysis of the thermal process, a 3-d finite element analysis model was developed. Using software ANSYS, the temperature field in LFW joint of 45 steel was established. Compared with the temperature field obtained from metallographic analysis, the simulation result was validated.
