摘要
针对现有平面形光幕探测装置无法测量任意方向飞行的破片速度问题,本文提出了一种探测幕面为环形的光幕测速装置构建方法.设计同圆心环形光源阵列与环形接收阵列,形成等间隔的2个圆柱形探测光幕面,准确测量任意方向飞行的破片速度.设计的装置中每个接收器件所接收的光照度值一致,消除了传统平面形光幕边缘光能量衰减的缺陷.结合现有光幕实现方法验证了测试方案的可行性,可有效探测任意方向飞行的破片速度.
Aiming at the current flat screen detector cannot measure the velocity of fragments flying in any direction,this paper presents the construction method with a circular screen of light screen speed measuring device.The circular ring light source and received array placed at the same center of circular are designed to form two cylindrical detection light screens with equal intervals.The device can measure the velocity of fragments flying in any direction.In the designed device,each receiving device receives the same illuminance values,which eliminates the defect of edge energy attenuation in the tradition flat detection light screen.The feasibility of the test project is validated by combining with the existing light screen implementation method,and the fragment velocity in any direction can be effectively detected.
