【摘要】 对静电陀螺球形转子在外受和未受大气压作用进行了理论和有限元数值分析。理论分析以弹性力学为依据,有限元分析对转子进行三维实体建模,并利用有限元软件ANSYS进行了变形分析与仿真,得出了上述两种状态下球形转子的静态变形,为补偿或减小转子的动态变形,提高转子的动态精度提供了理论依据。更多还原

【Abstract】 In this paper,deformation of spherical rotor suffered from pressure and without pressure in electrostatic gyroscope are analyzed in terms of theoretical and finite element numerical methods.Theoretical analysis is based on mechanics of elasticity.Three dimension solid modeling is built when we do finite element analysis.Two kinds of static deformation are derived by means of analysis of deformation and simulation of the finite element software ANSYS.It provides the academic material to amend or decrease deformation of rotor and increase dynamic precision of rotor.更多还原
