摘　　要：半球壳谐振子是半球谐振陀螺的敏感部件。如何固定，封装该谐振子有重要的实际意义。本文在详细分析谐振子振动的基础上，采用有限元法深入研究了它的支承结构，得到了支承杆对其振动特性影响的有关规律。基于减小支承杆弯曲振动对谐振子动力特性的影响，得到了ψ型结构最佳的重要结论。Abstract Hemisphericalshell resonator is the key component of HRG(Hemispheri-cal Resonator Gyro),And how to fix and package the above resonator is of significant actualvalue, On the basis of the analyses of the practical vibration feature of the resonator ,thispaper studies the actual supported structure of the hemispherical shell in detail by using fi-nite element method,and provides some related results,that the vibration of the shell wasaffected by the supported rod.Futhermore,an important result that the ψ type resonatoris the best structure was given,based on reducing the disturbance which is induced by bend-ing vibration of the supported rod. The results obtained here are of actual engineering valuefor developing HRG in home.
