The research is rooted in the overarching requirement for the launch stability of a specific piece of equipment. A high-fidelity digital prototype model was established. It was used to facilitate requirement decomposition, design validation, and system optimization. Core design metrics were refined through numerical simulation. A methodology centered on system requirement decomposition was developed. Mechanistic analysis of launch dynamics was enabled by the implemented digital prototype. Stability objectives were transformed into quantifiable key design parameters (e.g. servo mechanisms, vehicle body structures). Design indicators were verified via multidisciplinary co-simulation. Results confirm the efficacy of the methodology in identifying key design metrics that affect launch stability. Deterministic guidance is provided for equipment system design. Physical prototype testing is substituted with virtual validation. Equipment development efficiency and system design reliability are significantly enhanced.
近年来,数字样机技术在装备研制领域的应用成效显著。在中国,王国庆等[2]通过数字火箭技术构建全箭协同仿真模型,刷新了同类型火箭的研制周期纪录;梁艳等[3]提出基于模型的系统工程(model-based systems engineering,MBSE)的雷达数字样机设计方法,通过任务导向的指标分解实现多专业协同设计,有效验证了该技术在复杂装备中的应用价值。刘广利等[4]进一步表明,数字样机已成为装备研制的核心支撑技术。某装备的发射稳定性是其研制过程中的关键总体需求,该需求所关联的系统设计指标,直接影响装备的研制质量与作战使用效能,是牵引装备设计迭代升级的重要技术需求。然而,采用传统设计手段难以快速定位系统某一设计指标对发射稳定性的影响强度并实施精准优化,其核心原因在于对整个发射过程的机理分析不够深入——传统研发模式仅能开展散点式物理试验验证,无法构建全系统多学科耦合分析模型。为满足装备发射稳定性的研究需求,现从装备系统设计指标的分解辨识及优化提升角度出发,引入数字样机技术对该装备典型系统开展数字化建模与仿真应用研究。从系统总体设计目标与系统需求分解两个维度,细化对子系统的设计技术要求,旨在有效识别影响发射稳定性的核心设计因素,为典型子系统设计提供技术指导。通过建立“总体需求-系统指标-子系统参数”的全链条分析体系,实现对各设计指标影响烈度的量化评估,并依托数字样机完成全流程多学科耦合仿真,精准识别影响发射稳定性的核心因素。
