摘要
介绍了单自由度、多自由度振动系统的数学模型;阐述了傅里叶变换在研究振动系统任意非周期信号响应中的应用;研究了小波分析在振动信号处理中的作用;讨论了振动控制系统中的数学模型;为更好的运用数学知识解决振动问题奠定了理论基础。
The mathematical models for single-freedom-liner system and multi-freedom system are introduced.Fourier transform used in the application of any nonlinear signal response of vibration system is studied.The using of wavelet analysis in disposing signal is discussed.The mathematical model for the vibration control system is also discussed.This thesis lays a theoretical basis for better use of mathematics knowledge to solve the vibration problem.
