Application of Visualized Modal Testing Experiment for Practical Training Course

This paper proposes a practical training course system for modal analysis. Through this course, students could obtain both theoretical and practical studies for modal analysis. An experimental test rig to excite triangle plates is established. By using particles (such as rice or sand), the actual modal shapes of the triangle plates could be visualized. Compared with traditional modal testing practical course, the proposed course system is simple, straightforward and theory enriched. The actual implementation of this practical training course shows the effectiveness of the method to modal analysis education.
