Modeling method for design of diesel engine system based on MBSE

随着国防武器装备对动力要求越来越高,柴油机系统复杂度急剧提升,传统的以文档为核心的系统工程方法已经无法有效满足柴油机高效、准确、可靠的研制需求,为此,在柴油机研发过程中引入基于模型的系统工程(MBSE)方法。提出了基于RFLP的MBSE的柴油机系统建模流程,及支撑该流程运行的柴油机模型体系,在此基础上,以柴油机某研制任务为例,以模型为核心,给出了基于MBSE系统建模过程及模型实例,对柴油机需求分析建模、柴油机功能建模、柴油机系统架构分析与综合进行了阐述,体现了基于模型的设计方法在柴油机研制过程需求早期验证、功能快速仿真、数据可追溯方面的优势,从而有效提高研发设计效率。

With increasing demands for power systems in national defense weapons and equipment,the complexity of diesel engine systems has increased sharply.Traditional document-based system engineering methods can no longer effectively meet the efficient,accurate,and reliable development requirements of diesel engines.Therefore,model-based system engineering(MBSE)methods have been introduced into the diesel engine development process.This paper proposed a diesel engine system modeling process based on requirements-function-logical-physical(RFLP)and MBSE,as well as a diesel engine model system supporting the operation of this process.Based on this,the paper utilized a diesel engine development task as an example,and took the model as the core,providing the MBSE system modeling process and its model examples.The modeling of diesel engine requirements analysis,diesel engine function modeling,and diesel engine system architecture analysis and synthesis were elaborated.This demonstrated the advantages of the model-based design method in early verification of requirements,rapid simulation of functions,and data traceability in the diesel engine development process,thereby effectively enhancing R&D design efficiency.
