基于Marc的风力发电机主轴动力学特性研究
Research on Dynamic Characteristics of Wind Turbine Spindle Based on Marc
摘要
Abstract
In this paper,the vibration equation of a certain kind of wind turbine spindle was built according to the vibration theory.According to the problem of elastic support of bearing affecting the natural frequency of the spindle,two kinds of finite element model were set up,and the computational results were compared with using FEM software Marc for modal analysis.The contrast showed that every order natural frequency value is reduced with considering the elastic support of bearing,which means that the elastic support makes a great influence for the natural frequency value of spindle.Above all provide the basis for the further dynamics research.关键词
