| 摘 要： | 为快速得到拉锻式摩擦塞焊的焊接工艺参数，对焊接过程进行预测，建立了摩擦塞焊过程的扭矩、轴向力、功率和能量等指标的力学模型和热力耦合解析模型。模型的输入量为焊接塞棒的几何参数、材料属性、焊接转速和进给速度，输出量为焊接过程的扭矩、轴向力、功率和能量等。在自主设计的拉锻式摩擦塞焊设备上进行了焊接试验。通过将试验数据的输入和输出指标与理论模型值进行对比分析，验证了理论解析模型的可行性。

| Abstract: | In order to quickly obtain welding parameters of FPPW and predict welding processes, mechanics models and thermo-mechanics coupling analytical models of FPPW processes containing indicators such as torque, axial force, power, and energy were established. Inputs of this model were geometric parameters, material properties, welding speed, and feed speed of plug rod, and outputs were torque, axial force, power, and energy of welding processes. Welding tests were carried out on self-designed FPPW equipment. Feasibility of the analytical models was verified by comparing the inputs and outputs of welding data with the theoretical model. |
