摘　　要：利用有限元软件ANSYS的参数化分析技术,对大尺寸长条形超声塑焊焊头进行了优化设计。基于工程实际确定焊头长度、槽宽度及槽长度为设计变量,纵向谐振频率和频率间隔值为状态变量,振幅均匀度为目标函数,指出了编程中应注意的问题并给出了解决思路,最后编制了优化程序。通过优化设计实例说明该方法能很好地解决大尺寸超声塑焊焊头的设计问题,既缩短了设计周期,也降低了设计成本。The structure of large cross-section blade-like ultrasonic plastic welding horn was optimized using the finite element analysis package ANSYS. Based on engineering requisition,the optimum program was written applying the length of horn,the length and width of slot as design variables ,the longitudinal resonant frequency of horn and the frequency spacing as constraint condition,the uniformity of amplitude as objective function. Some essentials of program were presented and corresponding solutions were also given. The example of optimum design shows that this optimum method can solve well the design problem of large cross-section ultrasonic plastic welding horns ,and it not only reduces the design period but also cuts expenses dramatically.
