Abstract

The invention provides an overhead weapon station structure optimizing method based on an improved Kriging algorithm. The method includes the following steps of firstly, presetting the ranges of the elasticity modulus of a supporting frame, the mass of an ammunition can and the rigidity of a buffer; secondly, designing, selecting and obtaining N sets of sample points through a Latin hypercube test; thirdly, calculating vibration comprehensive parameters of gun muzzles; fourthly, establishing an initial training sample point set by combining the N sets of sample points with the vibration comprehensive parameters of the N gun muzzles; fifthly, optimizing a Kriging agent model through a genetic algorithm, and finding the optimal point and the maximum expectation improvement point; sixthly, optimizing the structural parameter optimizing problem on the basis of a duplex Kriging model sequence iterative optimizing algorithm till the algorithmconverges. By means of the method, through the optimization design of the elasticity modulus of the supporting frame, the mass of the ammunition can and the rigidity of the buffer, the disturbance quantity of the gun muzzles is made the minimum.

Description

technical field [0001] The invention belongs to the technical field of weapon stations, in particular to a method for optimizing the structure of an overhead weapon station based on an improved Kriging algorithm. 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...
