摘要
轴系摩擦力矩是影响陀螺轴承系统精度和可靠性的主导因素。为解决轴承组件在成对轴承安装过程中出现的摩擦力矩无法测试验证等问题,设计了一种陀螺轴系摩擦力矩测试仪。采用力矩平衡的测量原理实现了陀螺轴系的摩擦力矩测量。使用精密驱动系统、精密测量系统和定标校准系统,在计算机Windows操作平台下的LabWindows/CVI开发软件上进行编制,实现数据采集和处理。测试实验结果表明,陀螺轴系摩擦力矩测试系统通过长时间稳定性测试的最大差值小于0.01mN·m,满足了高精度、高可靠性、快速测量的要求。
Shaft friction torque is the dominant factor affecting the accuracy and reliability of gyro system, in or- der to solve the problems of the friction torque occur in the bearing assembly during the bearings in pairs installation process can not be tested to verify, designed a gyro shaft friction torque tester, adopting the measuring principle of moment balance realization of the friction torque measuring gyro shaft, using precision drive system, precision meas- urement system and calibration system, under Windows computer platform LabWindows / CVI software development carried out on the preparation, data acquisition and processing, carried out a self-test experiments. The results showed that： gyro shaft friction torque test system by the maximum difference is less than the long-term stability test O. OlmN ~ m, meet requirements of high accuracy, high reliability, fast measurement.
