| 转台作为检测与评价惯性导航仪器仪表的主要设备，其轴系静态刚度、动态特性和控制精度等直接影响到检测的可靠性和置信度。本文针对单轴位置转台，对轴承和驱动电机等关键部件进行了等效处理,利用软件ANSYS建立了有限元模型，通过静力学分析得到了转台简化模型的变形情况；通过模态分析得到其固有频率和振型，结果表明转台结构刚度较大，其固有频率远大于外部激励频率，可以避免共振，并为后续的结构优化做了基础。 |
| 英文摘要: |
| Turntable is one of the inertial equipment which can detect and evaluate navigation equipments, its shafting’s static stiffness, dynamics and control accuracy can affect inertial test's reliability and confidence directly. In this paper, firstly conduct bearing and drive motor of uniaxial position turntable, then simplify the finite element model using software ANSYS. Got the deformation of the simplified turntable by static analysis, natural frequencies and mode shapes by modal analysis, the results show the turntable has large rigidity, and its natural frequency is much greater than the external excitation frequency so as to avoid resonance, the finite element analysis is a foundation for subsequent optimization. |
