The device comprises a velocity measurement channel, a laser emitter, a laser receiver, a power supply, an oscilloscope, a high-speed camera and a computer. The velocity measurement channel is fixed at the exit of a bullet emission device, the laser emitter and the laser receiver are symmetrically fixed on the velocity measurement channel, the velocity measurement signal output end of the laser receiver is accessed into the input end of the oscilloscope, the signal output end of the oscilloscope is accessed into the high-speed camera, the high-speed camera is triggered through the signals emitted by the oscilloscope to realize the automatic triggering of the high-speed camera, and the speed of the bullet can be calculated through reading of the waveform on the oscilloscope. The camera observation and velocity measurement functions of bullets penetrating a target card can be realized, and the laser velocity measurement device with consideration to high-speed camera trigger function is high in accuracy and can be repeatedly used.

Description

technical field [0001] The invention belongs to the technical field of analysis and measurement speed control, and in particular relates to a speed measurement and shooting trigger device for a projectile penetrating a target plate and during the penetrating process. Background technique [0002] In the projectile high-speed impact target plate experiment, the speed of the projectile penetrating the target plate is a very important parameter, and observing the process of the projectile penetrating the target plate is also crucial for analyzing the deformation of the projectile and the target plate. [0003] At present, the methods for measuring the speed of projectile penetration into the target plate in my country include tin foil plate method, magnetic brush probe method and high-speed photography method. The production is cumbersome, time-consuming and labor-intensive, and the speed measurement of the tin foil target must require the projectile to be a conductor, which lim...
