基于正交试验设计的计转数定距弹数据处理方法

Turns-counting Ammunition Data Processing for Distance Determination Orthogonal Experiment Design

针对在实战条件下难以对所有弹道参数进行修正的问题,提出了利用正交试验设计进行数据分析的方法。该方法对影响计转数定距弹精确空炸精度的因素进行综合处理分析,减少了试验次数,确定了影响因素的相对重要程度。选取射距、初速、纵风和空气阻力系数四个影响因子进行仿真计算,仿真计算和理论分析结果表明,所选因子中,初速对计转数定距弹炸点精度控制影响最小,空气阻力系数影响最大。在恶劣的环境条件下进行实弹射击时,如果无法全部满足本文中四个因素的修正系数,可以按照空气阻力系数、射距、纵风和初速的顺序优先满足前者。

Aiming at the problem that correcting all ballistic parameters under real conditions is difficult.A method which used orthogonal experiment design to analyse datas was proposed.The number of trials were reduced and the relative importance of influencing factors were determined.In the paper,target range,initial velocity,range wind and coefficient of air resistance were selected for simulation and calculation.Simulation and theoretical analysis showed that the initial velocity had the least impact on the revolution and the air resistance coefficient was the most one.When if not all factors mentioned in this paper were considered under harsh firing environmental conditions,which could be in accordance with the air resistance coefficient,range,vertical wind and initial velocity.
