Influence of external load on forced vibration of rectangular plate

Rectangular plate is one typical structure with wild application in engineering, and the force vibration basis for analysis of sound radiation plate. In this work, numerical simulation conducted rectangular plate, influence external load also studied. Numerical results show that, will resonate under at certain driven frequency, it’s strictly related to structural modal frequencies. Structural response change obvious location load. When fixed, increase action region load, acceleration decrease some new resonance frequencies be observed. Conclusions here lay foundation further work on
