摘要:针对火炮出厂前的校瞄工作存在自动化程度不高、测试结果分辨率和精度低的缺点,设计了一种新型 微角偏移测试校瞄系统。该系统由位置灵敏探测器(PSD)、准直平行 管与二维精密旋转控制器构成。采用光电转换和信号处理技术,可实时获取火炮身管轴线的微角偏移量;利用相对简单的方法完成了高精度的测试,有效地改善了传统校瞄方法的不足。实验测试结果表明,该系统可在炮管仰角0°~70°范围内全程测试微角偏移量,其分辨率可达到0.001°,可广泛应用于不同口径火炮身管轴线的校瞄工作中。

Abstract:There are some shortcomings in aiming correction before the artillery leaves the factory, just like the low degree of automation, the low resolution and accuracy. Aiming at these problems, we design a novel laser micro angular deviation measurement and proofread aiming system. The system consists of position sensitive detector (PSD), collimating parallel laser tube and two-dimensional precision spin controller, and the micro angle offset of artillery bore can be acquired in real-time using the photoelectric conversion and signal processing technology. The traditional proofread aiming method can be improved effectively using relatively simple means to complete the high precision measurement. Experimental test results show that the system can detect the micro angle deviation with the barrel elevation range of 0°~70° in the whole course, and its resolution can reach 0.001°. It can be widely used to proofread aiming with different caliber artillery bore. -
