Abstract基于一阶剪切变形理论和哈密顿原理,建立了旋转层合圆板动力学运动方程和相应的边界条件。运用伽辽金法对旋转层合圆板横向振动的行波动力学特性进行了模拟,给出了其前行波、后行波振动频率随层合圆板铺层几何特征、材料参数、旋转速度等的变化规律,并对旋转层合圆板几何和材料参数对其动力失稳临界转速的影响进行了讨论。
Other AbstractBased on the first order shear deformation theory and Hamiltonian principle, the governing equations and boundary conditions of rotating multi-layer annular plate were derived. The analysis on dynamic characteristics of traveling waves for the rotating multi-layer annular plate is presented in this paper by means of Galerkin method. The frequencies of the forward and backward traveling waves for the rotating plate depend upon the rotating speed, and the geometrical and material parameters of the plate are obtained numerically. The effects of geometrical and material parameters on the critical speed of the rotating multi-layer annular plate instability are discussed in detail.
