- Abstract
The movement time of the projectile is the basic parameter for studying the gesture of the projectile. It is also the time base for the test of projectile shots. At the same time it is the time base for the test of gun vibration response. A test method for the moving time in the bore of a projectile which is based on the barrel strain test is proposed in this paper. First, paste a plurality of strain gauges along the axis of the barrel. Then take the rising edge time of the strain-time curve of each measuring point as the movement time of the Projectile. The artillery fired and the projectile moved at high speed inside. By testing the external surface strain time curve, and then through data processing, the time of a large-caliber artillery projectile in orbit was obtained. Through the firing test in the shooting range, the validity and correctness of the method are verified.
