摘要
针对小型战术导弹总体设计过程中学科耦合性强、计算复杂度高和难以得到全局最优解等问题,对多学科设计优化技术在总体方案论证中的应用展开了研究。首先,从工程实际的角度建立了小型战术导弹推进、几何外形、气动、质量、弹道等学科设计模型。其次,运用多学科可行法,在多学科设计框架OPTIMUS中进行了学科集成与工作流的搭建,实现了仿真分析流程自动化;然后,以小型战术导弹起飞质量最小为目标,采用差分进化算法得到了一组小型战术导弹最优总体参数,使导弹质量降低了11.6%,有效提高了导弹性能;最后,为探究导弹射程与起飞质量的耦合关系,以小型战术导弹质量最小和射程最大为目标,采用法向边界求交法进行了多目标优化设计,得到了系统的Pareto模型,为确定方案阶段小型战术导弹总体参数提供了参考。结果表明,多学科设计优化方法在小型战术导弹总体参数方案的论证中具备较强的工程应用价值。
Aiming at the problems of strong discipline coupling,high computational complexity and difficulty in obtaining opti⁃mal solutions in the overall design process of small tactical missile,the application of multidisciplinary design optimization technolo⁃gy in the overall scheme demonstration was studied.First of all,the design models of propulsion,geometry,aerodynamics,mass and trajectory of small tactical missiles were established from the perspective of engineering practice.Secondly,using the multi⁃disciplina⁃ry feasible,the discipline integration and workflow were constructed in the multidisciplinary design framework OPTIMUS,and the simulation analysis process was automated.Then,aiming at the minimum take⁃off mass of small tactical missile,a set of optimal over⁃all parameters of small tactical missile were obtained by using differential evolution algorithm,which reduced the take⁃off mass by 11.6%and effectively improved missile performance.Finally,in order to study the coupling relationship between missile range and take⁃off mass,with the minimum take⁃off mass and maximum range of the small tactical missile as the goals,the multi⁃objective opti⁃mization design was carried out by using the normal boundary intersecting method,and the Pareto model of the system was obtained,which provided a reference for determining the overall parameters of the small tactical missile in the program stage.The results show that the multidisciplinary design optimization method has strong engineering application value in the demonstration of the overall pa⁃rameter scheme of the small tactical missile.
