Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 As shown, the present invention proposes a measurement platform for missile mass and axial center of mass, including: two load cells, three distance measuring sensors and an engineering computer; two load cells are used to measure the two supports of the missile The quality felt by the point; three ranging sensors are used to measure the distance from the warhead to the front support point, the distance between the two support points and the distance from the rear support point to the tail of the projectile; the engineering computer is based on the data measured by the load cell As well as the data obtained by the ranging sensor, the length, total mass and axial center of mass of the missile are calculated.

[0031] The distance measuring sensor is realized by a laser range finder, and the accuracy is one ten-thousandth...

Abstract

The invention relates to a measuring platform and method for the mass and axial mass center of a guided missile. Forces sensed by two supporting points are obtained by a weighing sensor; a distance from the front supporting point to a guided missile head, a distance between the two supporting points and a distance from the rear supporting point to a guided missile tail are obtained by a distance measuring sensor. The measuring method solves the measuring problem of the guided missile mass and the axial mass center of the guided missile. The measuring platform has the characteristics of low cost, simpleness in operation, light mass, and high measuring precision.

Description

technical field [0001] The invention relates to a measuring platform and a measuring method for missile mass and axial centroid, which are used for measuring missile mass and axial centroid. Background technique [0002] In order to ensure that the missile has appropriate stability and good maneuverability to achieve high-precision missile attitude control and target strike, the mass center of the missile needs to be measured during the missile assembly test to ensure that the missile's center of mass is controlled within a predetermined area . [0003] In the project, the measurement of the axial center of mass of the missile mainly adopts the thin steel wire rope suspension method and the round rod support method. The principle of these two methods is that the gravitational moment on both sides of the fulcrum passing through the center of mass is equal. The principles of these two methods are clear, but there are large human errors in actual operation. Contents of the ...
