Modal Testing and Analysis of Vibrating Screens
摘要
Abstract
Modal analysis is a modern method to study the dynamic characteristics of structures.It is the application of system identification method in the field of engineering structure vibration.In this paper,the experimental modal analysis is done for a certain type of vibrating screens.The modal parameters,such as the natural frequency,damping ratio,modals and so on,are obtained.The problems in the design of vibrating screens are analyzed.This work provides a reference for subsequent modification of simulation models and structure optimization design of the screens.关键词
