Measuring Method of Artillery Radius of Rotation

Abstract

The invention provides an artillery turning radius measuring method and belongs to the field of artillery static detection. Turning radius accuracy of artillery can be improved through the method. The method includes the following measuring steps that the tested artillery is driven to a designated detection region, at least four evenly-distributed projection points are acquired, the artillery is leveled, a barrel is kept horizontal, a steering gear is rotated, and a point stroke is led out from the center of the end face of a muzzle to the horizontal ground through a plumb bob and marked; the distances between all the points are measured and recorded sequentially; the distances between all the points serve as the border length, so that a trilateration network is formed, trilateration network balancing processing is conducted, balancing results are converted into relative coordinates of the points, and finally the radius of a circle is acquired through fitting according to a least square principle and serves as the turning radius of the artillery. According to the artillery turning radius measuring method, field operation is simple, influences caused by point stroke position errors are reduced, use is convenient, and meanwhile measuring accuracy is guaranteed.

Description

technical field [0001] The invention belongs to the field of artillery static detection. Background technique [0002] The radius of gyration of the gun is the distance from the end face of the muzzle to the axis of rotation when the gun body is horizontal. It is used as a measured parameter to check the degree of deviation between the actual state of the gun and the design index during the range appraisal and type test. [0003] In the known technology, the national military standard with standard number 2977A-2006 provides a direct measurement method, which needs to predict the position of the axis of rotation of the measured artillery during implementation, and the position of the axis of rotation of the measured artillery is usually unknown, so , the direct measurement method is not easy to implement in the on-site inspection, and the indirect measurement method is usually used in the on-site inspection. [0004] The indirect measurement method provided by the national...

Problems solved by technology

At the detection site, the measurement of the chord length is easy to realize, but the measurement of the turret rotation angle requires the installation of an angle measuring instrument (such as a peripheral sight) on the center of rotation of the artillery. During the measurement process, the observer needs to repeatedly adjust the angle measuring instrument for observation Readings, these preparations and measurements take a lot of time. At the same time, the measurement accuracy of the turret rotation angle is not ideal due to the influence of factors such as the error of the position of the goniometer, the accuracy of the goniometer itself, and the error of manual readings.
