对高速旋转的轮盘建立了有限元模型,采用lanczos算法进行模态分析,得到其固有频率及振型,从而为其结构设计提供了依据。
The finite element model is established for the roulette rotating at a high speed. The lanczos algorithm is used to carry out modal analysis to get its natural frequency and vibration mode, which provides the basis for its structural design.
