Description

technical field [0001] The invention relates to a dynamic radius measuring mechanism of an arm-type precision centrifuge, which belongs to the technical field of precision instrument measurement. Background technique [0002] The precision centrifuge is a special large-scale precision testing equipment used in aerospace technology to provide a standard acceleration field for dynamic testing, calibration and calibration of inertial instruments. In the full-scale test of a large-g value accelerometer on a precision centrifuge, it is usually necessary to measure the dynamic radius of the precision centrifuge to complete the full-scale test of the accelerometer. The existing precision centrifuge dynamic radius measurement mechanism is that during the detection process, the measurement mechanism and the detection probe installed on the measurement mechanism are still, the precision centrifuge rotates, and the distance between the end of the precision centrifuge and the detection ...
