Combined with closure phase principle, the vibration characteristic equation was derived. Then, natural frequency, mode shape and bifurcation of frequency were given. Natural frequencies of static ring derived by wave propagation method are compared with the results of finite element analysis, which validates the wave propagation approach, and it provides a theoretical basis for dynamic calculation of bearing solid cage by wave propagation approach. Keywords:wave motion,thin ring with rectangular holes,propagation matrix,reflected matrix,transmitted matrix 查看全文  查看/发表评论  下载PDF阅读器
