Problems solved by technology

However, due to the surface contact between the support and the base, the frictional force is relatively large, which leads to a large error in the measurement of the center of mass position of the center of mass test device such as a missile by the center of mass testing device.

Abstract

The invention provides a centroid testing device and a method for determining the radian of a supporting piece, and belongs to the technical field of centroid measuring equipment. The centroid testing device comprises a base, a supporting piece and a bridge frame, wherein the supporting piece and the bridge frame are arranged on the base; the bridge frame comprises a measuring plate, a knife edge piece and a measuring rod piece; the measuring plate abuts against the supporting piece through the knife edge piece; the face, contacting with the base, of the supporting piece is an arc face; the arc face protrudes towards the base; and a centroid to-be-tested piece is placed on the measuring plate; and a pressure detector is arranged on the measuring rod piece and used for detecting the abutting pressure between the measuring rod piece and the base. The method for determining the radian of the supporting piece is applied to determining the radian of the supporting piece in the centroid testing device. According to the device and method of the invention, the accuracy of centroid position measurement of the centroid to-be-measured piece can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of centroid measuring equipment, in particular to a centroid testing device and a method for determining the radian of a support. Background technique [0002] With the continuous development of aerospace industry technology, the internal structure of missiles has become increasingly complex. The mass, center of mass and external dimensions of the assembled missile are important technical parameters in the final assembly. For example, the position of the center of mass of the missile is related to the internal structure of the missile and the distribution of ammunition, which directly affects the control of the missile trajectory and the accuracy of the missile hit. [0003] At present, the centroid test device is usually used to measure the center of mass of the object under test such as the missile. The centroid test device includes a base, a support, a measuring rod and a bridge. The bridge is in contact ...
