半球壳弯曲振动的分析
On Flexurar Vibration of Hemispherical Shell
-
摘要: 本文对半球壳的弯曲振动(频率)进行了详细地分析研究.给出了壳体两端边界角及壁厚变化时,谐振频率的变化规律.对于研制半球壳作为敏感部件的仪表如半球壳谐振陀螺仪有重要的应用价值.Abstract: This paper makes detailed analyses tor the flexural vibration (frequency) of the hemispherical shell and presents the varying laws of frequency with the rarving boundary angles and the wall thickness of the above shell, It is an important value to develop the instrument, such as hemispherical resonator gyro (HRG), whose sensing component is a hemispherical shell.
