摘　　要：传统应变能法能够快速识别并改进单个零件或单一系统的模态,但对于复杂系统,由于系统间存在紧密的耦合,传统应变能法难以取得很好的效果。因此提出了一种基于动能能量法的模态识别方法,仿真与实验对标结果表明,KE能量法能够快速识别复杂系统的模态,满足工程开发需求。Traditional strain energy method can quickly identify and improve the modal of a single part or a single system,but for complex systems,due to the close coupling between systems,the traditional strain energy method is difficult to achieve good results.Therefore,a new modal identification method based on KE(Kinetic Energy)theory is proposed.The simulation and test correlation results show that KE method can quickly identify complex systems'modal and meet engineering development requirements.
