Dynamic Radius Testing and Compensation Method for Precision Centrifuge Based on Internal Benchmark
In view of the key technical problems in the development of high-precision centrifuges,a dynamic radius measurement and compensation method based on internal reference was proposed.Through the combination of inductive micrometer and precision measuring rod,the high-precision measurement of dynamic radius was realized,and the regression analysis was carried out in Matlab environment to establish the mathematical relationship between dynamic radius and acceleration.The method improved the accuracy and stability of the centrifuge acceleration output,and met the testing needs of high-precision accelerometers.
