本文在考虑机械引信膛内点火机构的结构尺寸、工艺、性能等要求的基础上,建立了以最大安全落高和戳击速度为目标函数的有约束非线性多目标函数最优化数学模型。通过运用曲线拟合、非线性方程求根等数值方法,以及惩罚函数法、步长加速法等最优化方法,利用电子计算机进行了膛内点火机构的最优化设计。通过对某厂设计的82-××型引信膛内点火机构的计算,其结果表明,文中提出的设计方法能更快地得到比目前常用的方法更好的结果。
In this paper, based on the requirements of structural size, process and performance of ignition mechanism in mechanical fuze, the mathematical model of constrained nonlinear multi-objective function optimization with maximum safety clearance and pounding speed as objective function is established. By using numerical methods such as curve fitting, root equation of nonlinear equations, optimization methods such as penalty function method and step-by-step acceleration method, the optimization design of the ignition mechanism in the bore was carried out by using electronic computer. Through the calculation of ignition mechanism of a 82- × × type fuze chamber designed by a factory, the results show that the design method proposed in the paper can get better results than the current commonly used methods.
