摘要
利用ABAQUS软件对某海军舰船陀螺仪进行了模态分析.采用三维实体单元离散陀螺球,建立了陀螺球的有限元分析模型.分析了该陀螺仪的垂直环前6阶固有频率及振型,为陀螺球响应分析提供了重要的模态参数,同时也为结构的改进设计提供了理论依据.
The modal analysis has been carried on the ship＇s gyroscope using the ABAQUS software. It used the three-dimensional entity units to separate the gyroscope ball and establish the top ball finite element analysis model, analyzed the first six-order natural frequency and vibration mode of the vertical loop of this gyroscope ball, gave im- portant modal parameters for the top ball response analysis, and simultaneously provided the theoretical basis for improving the structural design.
