| 目的 研究磁脉冲焊接工艺参数对钢/铝传动轴焊接接头界面波形特征的影响规律，并优化设计焊接工艺参数。方法 采用光滑粒子动力学模拟方法分析接头界面波形，并以界面波形特征为目标，研究磁脉冲焊接时的工艺参数(扩口角度、放电电压、设备电容)对焊接接头界面的影响程度，并利用灰色关联度方法分析得出综合最佳工艺参数设置组合。结果 随着扩口角度的增加，钢/铝管轴连接界面波幅/波长值呈现出先升后降的趋势;放电电压增加，界面波幅/波长值增加;储能电容值对管轴碰撞速度影响不明显，连接界面波幅和波长变化不大。放电电压对界面成波区域长度的影响最大;各因素对波幅的影响程度为:放电电压＞扩口角度＞设备电容。结论 通过接头界面分析工艺参数对焊接强度的影响程度，对钢/铝传动轴扩口-磁脉冲焊接工艺设计具有理论指导作用。 |

| The work aims to study the effect laws of magnetic pulse welding process parameters on the waveform characteristics of the welded joint interface of steel/aluminum drive shaft and optimize and design the welding process parameters. The smooth particle dynamics simulation method was used to analyze the interface waveform of the joint. With the characteristics of the interface waveform as the target, the effect degree of process parameters (flaring angle, discharge voltage, and equipment capacitance) of magnetic pulse welding on the interface of the welded joint was studied. The gray correlation method was adopted to analyze and get the comprehensive optimal process parameter combination. With the increase of the flaring angle, the wave amplitude/wavelength value of the steel/aluminum tube shaft connection interface showed a trend of first rising and then decreasing; the discharge voltage increased, the interface wave amplitude/wavelength value increased; the energy storage capacitance value had no effect on the tube shaft collision speed; and the amplitude and wavelength of the connection interface did not change much. The discharge voltage had the greatest effect on the length of the wave forming area of the interface; and the effect degree of various factors on the wave amplitude was:discharge voltage>flaring angle>equipment capacitance. The analysis of the effect degree of the process parameters on the welding strength through the joint interface has a theoretical guiding role for the design of the steel/aluminum drive shaft flaring-magnetic pulse welding process. |
