求解变截面梁振动特性的假设模态法
Assumed Mode Method for Vibration of a Variable Cross-Section Beam with Lump Mass
摘要
Abstract
An analytical method for the vibration of the variable cross-section beam with an object fixed on the free end was developed and its calculation equation of natural frequencies,as well as the method for vibration mode functions was given. To verify the accuracy of this method,an engineering example was investigated and the natural frequencies were validated by making comparisons with those obtained by the finite element method. Consequently,it is observed that there is a good agreement be-tween the frequencies.关键词
