针对鱼雷热动力系统缺乏多学科集成设计环境,不能实现跨学科跨系统协同等问题,基于鱼雷热动力系统仿真的发展现状,提出了基于鱼雷热动力系统全工作过程联合仿真的预测设计方法,构建了涵盖不同维度、不同专业仿真软件和试验数据的动力系统仿真验证体系,探索了子系统数值仿真、方案优化和系统数值试验的预测设计途径,在实现多方案设计参数驱动和跨学科跨系统交互仿真的同时,完成了系统数字化验证和性能评价。通过仿真实例说明,该方法可以直观显示系统工作过程的流场细节和参数变化规律,完成系统性能的虚拟验证,实现从"传统设计"到"预测设计"的转变,提高设计成功率和可靠性,缩短研制周期,为鱼雷热动力系统的设计提供参考。
In view of lack of a multi-disciplinary integrated design environment for torpedo thermal propulsion system and inability to achieve interdisciplinary cross-system coordination,this paper investigates the co-simulation prediction design method on the whole working process of torpedo thermal propulsion system based on the development status of torpedo thermal propulsion system simulation.This study provides a simulation and verification system of the thermal propulsion system using different dimensions,different professional simulation software and test data,and explores the prediction design method of the subsystem numerical simulation,scheme design optimization and the system numerical tests,in realizing the drive of the design parameters and interdisciplinary cross-system simulation,completes the digital verification and performance evaluation.The simulation examples show that the method enables the visual display of fluid field details and parameter changes,thereby facilitating the virtual validation of system performance.Using this method,the transfer from the conventional design to predicted design is achieved.As a result,design success rate and product reliability are enhanced while the design period is reduced,which is crucial for the research and development of torpedo thermal propulsion systems.
