武器装备的动态性能是靶场鉴定、定型试验评价系统的重要技术指标之一,目前高速转管火炮及武器是新型的现代化武器;一个合格的身管武器在投入使用前都需要进行动态性能的测试,合膛身管在预定击发瞬间的实际指向与预定射向的偏离角度是测试身管武器动态性能的重要技术指标;为了解决转管速射武器以及带有稳定功能的炮塔武器在击发瞬间,身管的指向精度及其稳定性的测试难题,提出一种采用激光棱瞄配合光斑图像处理的测量方法来解决这个问题;详细介绍了该方法的身管指向测试原理及结构组成,通过建立身管指向的数学模型,深入分析了该结构的测量原理,经过搭建模拟实验装置并进行实验,在分析实验数据之后,计算出实验误差范围在3%以内,证明了该方法的可行性。

The dynamic performance of weapons is one of the important technical indicators of shooting range appraisal and type test evaluation system.At present,high-speed rotary artillery and weapons are new modern weapons;A qualified barrel weapon needs to be tested for dynamic performance before it is put into use,the deviation angle between the actual direction of the closed barrel at the scheduled firing moment and the predetermined firing direction is an important technical indicator for testing the dynamic performance of the barrel weapon.In order to solve the test problem that there are the pointing accuracy and stability in the tube fire weapon and turret weapon with a stabilization function at the firing moment,a measurement method using laser prism aiming and spot image processing is proposed to solve this problem;The test principle and structural composition of the barrel pointing of this method are introduced in detail.The mathematical model is established to analyze the measurement principle of the structure in depth.Through building a simulated experimental device and conducting the experiment,after analyzing the experimental data,the experimental error reaches within 3%,which proves the feasibility of the method.
