摘要
本文求出径向线性变厚度圆盘自由扭转振动的弹性动力学理论解,探讨了圆盘的无剪扭振和剪切扭振的特性,并给出不同厚度变化率和内外径比圆盘的固有频率和振型的数字计算结果。
The analytical solution of elastic dynamics for the free torsional viberation of the disk with a linear varible thickness in the radial direction is presented in this paper.The characteris- tics of the torsional vibration of the disk with and without shearing deformation along its thickness are investigated.The numerical results for the natural frequences and modes of the disk with various rate of change of the thickness and ratio of radius are also give.
