基于抗沉干预行为的舰艇进水过程建模与仿真

Time domain modeling and simulation of warship flooding process based on counter-flooding activities

  • 摘要:
      目的  实战损伤条件下,舰艇进水是舱室进水漫延与舰员抗沉行为相对抗的过程。现有的不沉性理论无法客观、全面评估抗沉干预对战损舰艇进水过程的影响,缺少从全时域的角度对战损舰艇进水过程开展预测的手段。
      方法  首先,分析抗沉干预下舰艇破损进水的耦合关系,构建进水过程时域模型,进而给出数值求解算法;其次,结合案例分析抗沉干预要素对不沉性的影响,并开发可视化、交互式的仿真系统。
      结果  通过仿真系统实现了进水过程与多种抗沉干预方式的综合评估,是对现有不沉性理论的有效补充。
      结论  该成果不仅可帮助设计人员掌握抗沉设计方案对干预进水过程的有效性,指导舰艇抗沉能力的设计;还可应用于抗沉指挥决策的态势预报,具有较高的军事应用价值。

     

    Abstract:
      Objectives  Warship damage flooding is an interactive process between progressive flooding and counter-flooding measures under battle-damaged conditions. Traditional damage stability theory cannot simulate the influence of counter-flooding measures on the damaged warship flooding process, and there is no method for predicting this process in the full-time domain.
      Methods  By analyzing a coupling relationship between the damage flooding process and counter-flooding measures, a flooding process time domain model is established and a numerical solving algorithm obtained. Case studies are analyzed on the basis of the model and algorithm, and an interactive visual simulation system is developed.
      Results  The simulation systemcan comprehensively assess the flooding process and various counter-flooding measures, providing an important supplement for warship damage stability theory.
      Conclusions  This study can help designers to understand the effectiveness of counter-flooding design schemes on the flooding process and guide the design of counter-flooding systems. In addition, it can be used for shipboard flooding decision-making, giving it high military application value.
