| 摘 要： | 超声强化能有效地提高工件的疲劳极限,延长其疲劳寿命.丸粒速度是影响超声喷丸强化效果的重要因素,而变幅杆振幅的提高可以显著地提高丸粒速度.以提高变幅杆振幅为目的,用解析法设计了级联式变幅杆;在此基础上,用ANSYS软件对其进行了动力学分析,得到了比单一变幅杆更大的振幅放大比.

| Abstract: | Ultrasonic peening is a special metal surface treatment intended to extend the fatigue life of most machine components.The shot speed,which can be increased by enhancing the amplitude of horn,is an important factor to intensifying the effect in ultrasonic shot peening.A composite horn is designed theoretically to increase its magnification ratio.Simultaneously,its dynamic characters are obtained theoretically by using finite element method.Comparing with single horn,the composite horn based on finite elemen... |
