摘要
对一类轴对称圆环的面内弯曲振动进行了分析计算,给出了圆环面内弯曲振动固有频率表达式。利用ANSYS软件对含有直梁段圆环的面内弯曲振动进行了有限元模态分析。结果表明,含直梁段圆环的弯曲振动,当选取适宜的结构参数时,总可以找到频率差几乎为零的近似正交模态。
The flexural vibration of a circular ring that is of axis symmetry is analyzed and calculated, the solid frequency expression of the flexural vibration is obtained. The mode of flexural vibration in circular ring in the plane of the ring which has straight sections is analyzed using ANSYS software. The result expatiates that this kind of flexural vibration can always find near orthogonal modes bearing difference of frequencies of almost zero when proper parameters are selected.
