Rotational inertia error detection device and method based on centrifugal force method

The invention discloses a rotational inertia error detection device based on a centrifugal force method. The device comprises a measuring platform disposed on a rack, the measuring platform is supported on the rack through a bearing, the central part of the measuring platform is connected with a drive shaft, the drive shaft is sleeved with a secondary inertia disc, the measuring platform and the secondary inertia disc are coaxially driven by a driving shaft, the driving shaft and an output shaft of the driving motor are coaxial, the driving shaft is externally connected with a rotational inertia error display screen of an external controller, and a measured object is arranged at the center of the measuring platform. The device is low in cost, simple in structure and easy to operate. The invention further discloses a detection method of the rotational inertia error detection device based on the centrifugal force method, and the method is high in detection precision and high in detectionefficiency. 本发明公开了一种基于离心
