Abstract

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.

Description

technical field [0001] The invention relates to the technique of measuring the moment of inertia, in particular to a moment of inertia error detection device and detection method based on the centrifugal force method. Background technique [0002] The moment of inertia is the measurement of the inertia of a rigid body when it rotates around its axis (revolving object maintains its uniform circular motion or static characteristics). Minimize the moment of inertia error to ensure product quality. The existing technology for measuring the moment of inertia error has a complex structure, cumbersome operation, low detection efficiency, and low detection accuracy. Contents of the invention [0003] The object of the present invention is to provide a rotational inertia error detection device and detection method based on the centrifugal force method in view of the deficiencies in the prior art. The device has low cost, simple structure and easy operation. This method has high d...

Problems solved by technology

[0002] Moment of inertia is the measure of inertia when a rigid body rotates around its axis (the characteristic that a rotating object maintains its uniform circular motion or is still), represented by the letter J, and its value depends on the shape, mass distribution and position of the rotating shaft of the object, which is required in production Minimize the error of the moment of inertia to ensure product quality. The existing technology for measuring the error of the moment of inertia has a complex structure, cumbersome operation, low detection efficiency, and low detection accuracy.
