中文摘要:
      谐振频率、频率间隔性、振幅均匀度是大尺寸超声塑料焊接工具头设计中的几个主要指标。基于工程实际,以工具头纵向长度、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,利用有限元软件ANSYS的参数化分析技术,对大尺寸立方体超声塑焊开槽工具头进行了优化设计。结果表明,该优化方法能很好地解决大尺寸超声塑焊工具头的设计问题,既提高了设计效率,也降低了设计成本。
英文摘要:
      The resonant frequency,frequency spacing and the uniformity of amplitude are important quality specifications of large size ultrasonic plastic welding horns.Based on engineering requisition,considering 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 conditions,and the uniformity of amplitude as the objective function,the optimal design algorithm is written.The structure of large size block-like slotted horns for ultrasonic plastic welding is optimized by using the finite element analysis package ANSYS.The example of design shows that this optimized method is feasible and effective to solve the design problem of large size block-like slotted horns for ultrasonic plastic welding.
