摘要:
针对火炮摇架多目标优化设计问题,在某火炮上装部分的结构有限元动力学模型的基础上,利用神经网络方法建立优化变量、误差变量与优化目标函数之间的数学模型。采用双层嵌套的优化求解方法,以炮口扰动和质量为目标,对摇架结构尺寸进行不确定性优化,考虑其弹性模量、密度、泊松比等材料特性参数误差。因为用目标函数区间中点值和半径值判断设计变量的优劣,该文方法优化结果大部分略高于现有的火炮结构优化方法,更具稳健性和可靠性。
Abstract:
A mathematical model between the design variables,the error variables and the objective function is built using neural network method based on a structural finite element dynamic model of a gun aiming at the multi-objective optimization problem of cradle carriage of the gun.A two-layer optimization method is used to solve the uncertainty optimization problem of the structure and size of the cradle carriage with the mass and the muzzle disturbance as the goals,and the material property parameter errors such as elastic modulus,density and Poisson’s ratio are considered.Most of the optimization results of this method are higher than those of the existing optimization methods because the design variables are adjusted by the midpoint and radius of the object function interval,and this method is more steady and reliable.
