SiC/Al技术延长惯性平台标定周期的理论研究

平台漂移误差测试和标定是保证惯性系统精度最基本的措施之一，应用于武器载体特别是战术弹时，要求尽量延长标定周期。在长期存储过程中，陀螺、加速度计等惯性元件测量轴的安装精度会因安装应力和自重应力作用而有损失，使平台漂移模型失真。理论分析表明，复合材料技术可大大减小此类误差，从而可通过长期保持惯导系统机械零位精度来延长平台标定周期。

Theoretical Study on Extending Inertial Platform Adjustment Period by SiC/Al Technology

Drift error measurement and adjustment of inertial platform is one of the most important processes, which can ensure the positioning accuracy of INS. This adjustment period should be as long as possible according to military users requirements. However, during long-time storage, the input axis fixing error of inertial elements may become larger because of fixing and weight stress. Theoretical analysis shows that MMCs can remarkably reduce such errors through high stability of mechanical accuracy. Thus a longer period of inertial platform adjustment can be achieved.
