主 题:spinning cylindrical shell nonlinear free vibration arbitrary boundary condition Chebyshev polynomial Sanders’shell theory
摘 要:The aim of the present study is to investigate the nonlinear free vibration of spinning cylindrical shells under spinning and arbitrary boundary *** springs are used to simulate arbitrary boundary ***’shell theory is employed,and von Kármán nonlinear terms are considered in the theoretical *** using Chebyshev polynomials as admissible functions,motion equations are derived with the Ritz ***,a direct iteration method is used to obtain the nonlinear vibration *** effects of the circumferential wave number,the boundary spring stiffness,and the spinning speed on the nonlinear vibration characteristics of the shells are *** is found that there exist sensitive intervals for the boundary spring stiffness,which makes the variation of the nonlinear frequency ratio more *** decline of the frequency ratio caused by the spinning speed is more significant for the higher vibration amplitude and the smaller boundary spring stiffness.
