超声喷丸中矩形截面复合型变幅杆的动力学特性研究

摘要

A rectangular cross-section composite horn is designed theoretically to increase its cross-sectional area, improve the efficiency and so on. On this basis, its dynamic parameters are obtained theoretically by ANSYS. Through the comparative analysis, it turns out that FEM will be an efficient method to be used to design composite horn with complicated intersection.%为了改善超声喷丸过程中变幅杆输出端的端面面积,提高喷丸效率,用解析法设计了一种矩形截面复合型变幅杆,计算了其动力学参数.在此基础上,运用ANSYS有限元分析软件对其进行了动力学分析,求得了相应的动力学参数.通过对比分析,证明了用ANSYS设计变幅杆的可行性,为复合型变幅杆的设计提供了一种有效的方法.
