Abstract :
Current measurement method of warhead fragments velocity has some problems. Therefore, a new measurement method based on parallel net target is proposed. This test system consists of resistance, metal wire, circuit boards, frame and data acquisition display device component. The design of resistance nets is the core of this device. Each unit is connected by a resistor in series with a metal wire, number of these units parallel form resistance network. When the fragments fly through the parallel net target, the oscilloscope records the time and the voltage difference at which every fragment flies through the screen. According to the acquired waveform and the parallel net target parameters, the velocity vector and size of every fragment are calculated, and then the velocity vector of the fragments can be calculated accurately, which is helpful for calculating the accurate initial velocity and the attenuation coefficient of warhead fragments. This method is verified to satisfy the request of bullet velocity measurement.
