摘要

摘要: 研制了用于测量二级轻气炮毫米级弹丸速度的遮挡式激光测速系统。该系统主要包括测速平台和激光测速仪，采用红光半导体激光器作光源，硅光电二极管为光电探测器。测速平台安装于炮管测速段，具有结构简单紧凑、抗振动、激光光幕易于准直和测量等特点。激光光幕高度为20 mm，避免了弹丸偏离轴线过多时因无法遮断光束导致的测速失败。运用该测速系统进行了一系列二级轻气炮测速实验，成功测量了金属弹丸和非金属弹丸的速度，测速范围为1.58～4.51 km/s。将测量数据与磁测速系统测量数据进行比较，结果表明，该激光测速系统的测量精度高、稳定性好、灵敏度高、抗干扰性强、适用范围广。

Abstract: A new velocity measurement system is set up for measuring the millimetresized projectile velocity in two-stage light gas gun. The system consists of an installation platform and a laser velocimeter which using red light semiconductor laser as lamp-house and silicon photodiode as photodetector. The platform installed in the barrel test section has numerous advantages of simple structure, aseismic design, easy adjustment and measurement. Using this new measurement system, the metallic and non-metallic projectiles velocities are successfully achieved. Moreover, the velocities of metallic projectile measured by this system are compared with those using magnetic induction sensors. The results show that this system not only has high reliability and accuracy but also high sensitivity, strong anti-interference and wide range of applications.
