为提高**火控静态性能指标的测试精度, 设计了火控性能参数静态测试系统, 用于对火炮炮身松动量、过渡过程品质、刚性、漂移速度及最大调炮速度等参数进行测试。通过相对测试的方法, 运用光学测量头拍摄炮口在坐标靶上的相对运动图像, 计算出相关参数。采用弹性胀套的连接方式, 实现了静态测量头的可靠安装及方便拆卸。结果表明: 在-30℃～+50℃环境温度下, 光学系统的MTF值可达0.6以上, 接近系统的衍射极限;当2ω=9.15°, f′＝50 mm时, 静态测角精度σ≤0.2 mil。安装夹具适应100 mm、105 mm、125 mm火炮的固联安装, 测试系统可对某型坦克炮管的相关指标进行实测, 也可广泛应用于高炮、装甲车辆、舰载火控系统、坦克等多种**装备。

To improve static performance indicators of weapon fire control system, a static testing system was developed to test loosened quantity of cannon barrel, transition process quality, rigidity, drift velocity, and maximum moving speed and other parameters. An optical measuring head was used to capture the images of muzzle relative motion on the coordinate by a relatively method, the parameters were calculated accordingly. Elastic sleeve was used to achieve reliable installation and easy removal of the static measuring head. Results show that: In -30℃～+50℃ environment, the modulation transfer function (MTF) value of the optical system is more than 0.6, which is closing to the diffraction limit; When 2ω=9.15°, f′＝50 mm, the static angular accuracy σ≤0.2 mil, which meets the technical requirements. The mechanical fixture is suitable for fixed connection with 100 mm,105 mm and 125 mm artilleries. The system can not only measure some parameters of XX model tank barrel, but also be widely used in anti-aircraft artillery, armored vehicles, shipboard fire control systems, tanks and other weapons.
