高低压内弹道优化设计

The Optimization Design In Interior Ballistic of an High-Low Pressure System

本文以高压室最大压力P_(Im)Ⅱ和低压室最大压力值P_(2m)作为优化目标函数,以高低压系统的主要结构参数(喷孔直径d_1、高压室内半径r、高度H、高压室衬片厚b、弹丸挤进压力P_0和高压空壁厚S_0)为优化参数.組成双目标有约束的优化数学模型.用加权求和法选优,用复形法编制计算程序上机计算.然后根据优化结果和工艺要求调整各项内弹道结构参数.用此法选择高低压系统内弹道设计方案比较理想有效.

In this paper,it is discussed that called optimization design in the interiorballistic of high—low pressure system.The optimization objects are mian structuralparameters of high-low pressure system that includes the diameter of nozzles (d_1),theinterlor radius (r) and heighit (H) of high pressure chamber,the shot—start pressure(Po),the thick of liner (b) and that of wall of the high pressure chamber (So).Themaximun pressures of high and low chamber (P_(1m),P_(2m))are targeted for functions.Themethod of add right extract sum is used when the mathematical models are made.Thenthe results are calculated by computer.Finally,it will be taken to revise the results of cal-culation according to the technological requirements.The ideal effects would be ob-tained,espically in the option design programme.
