Four-screen accuracy target structure assembling and parameter measuring method

Abstract

The invention relates to a four-screen accuracy target structure assembling and parameter measuring method, aiming at solving the problem of large measured error due to inaccurate structure parameters in assembly and practical use of the conventional four-screen accuracy target. The method adopts a technical scheme comprising the following steps of: (1) adjusting a laser sight of a transmitting and receiving device to ensure speckles of the laser sight are superposed; (2) adjusting to ensure that a light screen I, a light screen II and a light screen IV are vertical to the plane, and the light screen I is parallel to the light screen IV; and (3) adjusting the light screen I and the light screen II to measure an angle alpha related to X, and adjusting the light screen I and a light screen III to measure an angle beta related to Y. By adopting the method, a virtual reference plane is constructed by adopting two laser levels, reference or three mutually-vertical external reference planescan be prevented from being set or constructed on a mechanical structure, namely a hexahedral support structure, so that the requirement for processing and assembling accuracy of the hexahedral support structure is relaxed. The measured structure parameters are accurate by adopting the method, so that measurement errors are avoided.

Description

Four light curtain precision target structure assembly and parameter measurement method technical field The invention belongs to the technical field of ballistic parameter testing outside the shooting range, and mainly relates to an adjustment method of a projectile shooting density measurement device, in particular to a structure adjustment and parameter measurement method of a four-light curtain precision target. Background technique Standing target shooting density is an important indicator to measure the performance of low-elongation ballistic weapons. The traditional density measurement mostly adopts contact measurement. Materials such as wood board, cardboard or textile cloth are vertically erected at the predetermined measurement position along the ballistic trajectory. A target, The weapon being evaluated shoots at the target, and the accuracy of the weapon is judged by manually measuring the position of the bullet hole on the target. This method has low measuremen...
