摘要
对超声变幅杆的设计进行了理论分析,着重计算了指数形变幅杆的振幅放大系数、节点及应力极大点等参数。采用有限元软件ANSYS对变幅杆作了模态和谐振分析,得到的结果与理论结果比较,满足工程设计的需要。为超声变幅杆的设计和优化提供了新的途径。
By theoretical analysis of ultrasonic amplitude horn, calculate magnifying coefficient of amplitude, nodal position and maximum stress position of exponent type horn. FEM is used to analyze the modal and resonant vibration of the horn with ANSYS. Compared with theoretical results, it is satisfied with demands of engineering. A new way is carried out for design and optimality of the horn.
