精密离心机半径值动态测试系统

Dynamic measurement system for the radius of precision centrifuger

精密离心机半径值动态测试系统采用量块法测量其静态半径值，与动态下利用线位移传感器组件测量其微位移量之和的方法相比较，其工作半径值测量的相对误差达３．３×１０￣（－６）。对静态半径测量所采用的量块法及动态下采用线位移传感器组件测量补偿量的原理、方法、数据处理及误差分析进行了详细论述。此法可推广应用到其他类似的大量程动态测试系统中。

In dynamic measurement system for the radius of precision cen-trifuger,the gauge block is adopted to measure its statics radius,and linear dis-placement sensor assembly is used to measure its sum of diffirential displace ments for dynamic. In this way,the relative error of working radius is 3.3 X×10￣(-6). In this paper,the principle,methods,data processing and error analysis are described.This method can be applied to similar large scale dynamic mea-surenment system.
