摘要
该文论述了模态分析的基本理论,结合SISO状态空间系统,提出了一种实时分析结构物振动模态特性的方法。并通过货车车架的例子,阐述其应用方法,为车架的设计提供理论依据,为其他振动特性分析提供一种新方法。
This article discusses the basic theory of modal analysis,combined with SISO state space system,a real-time analysis of modal characteristics of structures approach.And through the example of truck frame,described the application of methods,provide theoretical ba sis for the design of frame,also provide a new method for the analysis of vibration characteristics of the other.
