摘　　要：半球壳是新型半球谐振陀螺的敏感部件．有效地隔离谐振子有害的耦合振动对于保证陀螺性能的可靠、稳定具有十分重要的工程价值．本文在研究半球壳谐振子支承杆结构振动的基础上，采用瑞利－里兹法（Ｒａｙｌｅｉｇｈ－Ｒｉｔｚｍｅｔｈｏｄ），对结构特性最佳的Ψ型谐振子最低阶耦合振动进行了分析，给出了谐振子有关参数设计的近似解析工程用方程．Hemispherical shell resonator is the key component of HRG (Hemispherical Resonator Gyro). And it is of actual significant engineering value to isolate the harmful coupling vibration of resonator effectively for HRG. On the basis of analysis of the supported structure vibration feature for hemispherical shell resonator, this paper studies the coupling vibration of the most optimal Ψ type hemispherical resonator by using Rayleigh Ritz method. Furthermore, this paper provides the actual engineering equations to design related parameters of hemispherical resonator. The obtained equations here are of actual engineering value for developing HRG in home.
