Problems solved by technology

However, due to the very complex structure of the artillery, in order to carry out modeling and simulation, many assumptions must be artificially made to simplify the actual structure, the model will inevitably have errors with the actual structure, and the simulation calculation results will also have errors
When the model is not validated by experimental results, its error may be large

Abstract

The invention relates to a muzzle angle vibration response test method and a muzzle angle vibration response test system. The method comprises the following steps: a detector is used for outputting the height and a horizontal vibration angular displacement of a muzzle; an angular speed sensor performs integral operation on an angular speed signal of a rocking bracket to obtain the height and a horizontal vibration angular displacement of the rocking bracket; a recoil displacement sensor obtains a recoil displacement of the muzzle, thus obtaining a vibration angular displacement absolute value of the muzzle. The system is realized based on the method. According to the method and the system, a test value of the vibration angular displacement of the muzzle under a working condition of shooting at any shooting angle can be obtained, and reflects the real characteristic of the vibration angular displacement of the muzzle; the sensor is arranged on the rocking bracket, so that the test process is simplified, and the test efficiency is improved; to verify a muzzle design effect and develop a rule that a gap of a gun mechanism affects the gun shooting density, test parameters and a test method are provided; a test method support is provided for increasing the gun type research level in China.

Description

technical field [0001] The present disclosure relates to angle measurement, and in particular, to a method and system for testing muzzle angle vibration response. Background technique [0002] The muzzle vibration response is one of the key factors affecting the firing intensity of the artillery, and the small muzzle vibration response is the basic guarantee for the high performance of the artillery firing intensity. The angular displacement of muzzle vibration is one of the important response quantities. [0003] Due to the randomness of the vibration response of the muzzle, the randomness of the muzzle firing angle and shooting direction when the projectile exits the muzzle is caused, resulting in the random distribution of the projectile dispersion. When the artillery is firing, if the measurement technology can be used to accurately obtain the angular displacement response of the muzzle vibration, it will be of great significance for evaluating the shooting effect of th...
