数值计算在武器效应与毁伤评估研究中的应用简析

Brief Application Analysis of Numerical Computation in Weapon Effects and Damage Assessments

数值计算是武器效应与毁伤评估研究的重要途径,其作用集中体现在指导试验设计、优化方案,拓展试验结果及作为理论与试验研究的补充手段三方面。由国外武器效应数值计算软件的基本特点与国内效应计算软件的发展现状可知,国外商业软件的突出优势是研发力量强、操作方便、计算精度与结果可靠性高,前、后处理软件丰富,且计算并行化。从总体上看目前我国数值计算仍受制于人,在基础数据、求解规模、计算能力、二次开发四方面发展相对滞后;基于开源数值计算软件包进行二次开发是迅速缩小与国外成熟软件差距的有效途径。

Numerical computation is an important way to study weapon effects and damage assessments.Its function is mainly reflected in three aspects:guiding test designs,optimizing schemes,and expanding test results as a supplementary means of theoretical and experimental researches.According to the basic characteristics of foreign software and the development status of domestic software for numerical computation of weapon effects,the outstanding advantages of foreign commercial software are strong research and development ability,convenient operation,high calculation accuracy and reliability,rich pre-processing and post-processing software,and parallel computing.On the whole,the numerical computation research in China is still restricted by others.Meanwhile,the developments of basic data,solution scale,computing ability and secondary development are relatively lagging behind.In order to overcome the bottlenecks,the secondary development technique based on open source numerical calculation software package is an effective way to rapidly narrow the gap with the mature foreign software.
