Establishment of Mathematical Model for Compressor Blade Vibration and Research on Vibration Dynamic Characteristic
摘要
Abstract
In order to study dynamic characteristic of compressor blade under exciting force influence,a mathematical model for compressor blade vibration is established by combining basic parameters of some gas turbine blade. By means of simula-tion on Simulink platform of MATLAB software,the vibration displacement curve of blade affected by exciting force is ob-tained under conditions of constant and variable speed rotation. Results indicate that under constant speed condition,differ-ences of images of synchronous vibration and asynchronous vibration are great,the vibration displacement amplitude of blade under high frequency exciting force is far less than that under low frequency exciting force and it is able to identify vi-bration characteristics of multiple resonance regions under the condition of variable speed sweeping.关键词
