| 摘 要： | 在结构声辐射的主动控制中，以矩形板结构压电陶瓷为次级分布力源，首次建立具有最佳抑制声辐射效率的分布压电振动力学模型，在此模型基础上实验分析了简支状态下的模态效应，这为ＴＭＳ３２０Ｃ３０信号处理系统的有源结构声辐射控制试验系统解决了重要理论问题，该系统较之以点力为次级力源系统前进了一大步，并具有通用性。

| Abstract: | In active structural acoustic control the rectangular plate which has distributed PZTs as secondary actuators is studied and the distributed piezoelectric vibration dynamic model with the best sound radiation efficiency abatement is built. The experiment and analysis of simple support thin rectangular plate's modal responses are made based on this model. It solves important theoretical problems for active structural acoustic control which adopts TMS320C30 signal processor system. This model system is a great progress as compared to point actuator system. It has property in common use. |
