Abstract

The invention provides a weapon station muzzle disturbance optimization method based on the Kriging algorithm. The method comprises the steps of: firstly, setting the ranges of the buffer damping, the barrel elasticity modulus and the barrel Poisson ratio of an overhead weapon station; secondly, selecting N sample points by using the Latin Hypercube experiment design; thirdly, calculating a muzzle disturbance comprehensive function; fourthly, combining the N groups of sample points and N muzzle vibration comprehensive parameters to form an initial training sample point set; fifthly, performing optimizing on a Kriging surrogate model by using the genetic algorithm to find out the optimal point and the expectation maximum raising point and obtain optimized structure parameter values. The weapon station muzzle disturbance optimization method based on the Kriging algorithm can minimize the muzzle disturbance quantity through the optimization design of the elasticity modulus of a support frame, the quality of a cartridge box and the rigidity of a buffer.

Description

technical field [0001] The invention belongs to the technical field of weapon stations, in particular to a Kriging algorithm-based muzzle disturbance optimization method for weapon stations. Background technique [0002] When the artillery is fired, the instantaneous high temperature and high pressure generated by the combustion of the gunpowder pushes the projectile to move at high speed in the chamber, and the inertia of the artillery causes the artillery to vibrate violently, resulting in changes in the direction of the muzzle, which seriously affects the shooting accuracy. Studying the muzzle disturbance and its changing law of artillery firing has important theoretical significance for evaluating and examining artillery performance, appraising artillery production quality, and improving artillery shooting accuracy. The muzzle disturbance is minimized by optimizing the structural parameters of the overhead weapon station. Contents of the invention [0003] The inventi...
