基于VXI总线的陀螺仪加电测试技术研究

Gyros Dynamic Test Technology based on VXIbus

选用适当的VXI硬件模块和合理的软件结构体系,构建了基于VXI总线的动力调谐陀螺仪测试平台,采用在陀螺仪力矩器上加指令电流的方法标定陀螺仪的角加速度动态误差系数项。通过理论分析,证明这种方法是可行的,为陀螺仪动态误差系数的标定提供了更为经济实用的方法,同时对实现陀螺仪的机内测试,也提供了一条有效的途径。

A testing platform based on VXI modular was constructed to test the dynamic tuned gyro. The dynamic error of gyro＇s angular acceleration coefficients is calibrated by applying current instruction to gyro＇s torque implement. This method is proved to be feasible theoretically, which provides a practical and economical way to calibrate the coefficients of the gyro＇s dynamic error. At the same time, it is also an effective method to realize the BIT （built in test） of the gyro.
