摘　　要：针对超声塑料焊接变幅杆因加工对象不同而存在的设计难题,结合具体工程案例,综合了基于纵波传输理论的复合变幅杆的参数化建模、有限元模态与谐响应分析,阻抗分析与实验分析的一体化方法,实现了圆锥复合变幅杆的设计、建模及结构优化的高效性,准确性。结果表明:采用嵌入参数的建模可以更快的实现复合变幅杆结构设计及优化;有限元分析与阻抗分析方法在复合超声变幅杆的振型、频率特性分析上吻合度较高,试验测试满足设计要求;可以为单头超声塑料焊接复合变幅杆提供通用的设计、分析方法。In view of the design of ultrasonic plastic welding horns due to different processing objects, combined with the specific engineering case, integrated with the method of parametric modeling based on longitudinal wave transmission theory, finite element modal and harmonic response analysis, impedance analysis and experimental analysis, the efficiency and accuracy of the design,modeling and structure optimization of the conical composite horns are realized. The results show that the structural design and optimization of the composite horn can be realized more quickly with the parameters. The results also show that the finite element analysis and impedance analysis is in a good agreement with the vibration mode and frequency characteristics of the composite ultrasonic horn, and the experimental test meets the design requirements. It can provide a universal design and analysis method for the single-head ultrasonic plastic welding composite horn.
