摘要
多电飞机对机电系统的研发周期和系统集成后的各项性能指标提出了更高的要求,传统的研发模式难以满足新型飞机系统的设计需求。建模与仿真能够在机电系统研制早期,实现对系统功能、性能进行评价,可以有效缩短系统研制周期,降低系统研制风险,进行系统综合优化设计。针对多电飞机机电系统多学科、多领域、复杂程度高的特点,采用联合仿真的方式开展系统集成化的运行特性分析,解决了复杂大系统仿真固有的仿真速度慢、收敛性差、仿真精度低等问题。基于联合仿真技术开展系统级的虚拟仿真试验,全面的覆盖工况需求,可以实现系统的快速验证与迭代。以多电飞机供电系统与电静液作动器(EHA)耦合特性虚拟仿真试验为例,验证了该模式的可行性。
More electric aircraft has higher requirements for the R&D cycle of electromechanical system and the performance indicators after system integration.The traditional R&D mode is difficult to meet the design requirements of new aircraftsystem.Modeling and simulation can evaluate the system function and performance in the early stage of electromechanical system development,effectively shorten the system development cycle,reduce the risk of system development,and carry out the comprehensive optimization design of the system.Aiming at the characteristics of multi-disciplinary,multi-field and high complexity of more electric aircraft electromechanical system,the distributed heterogeneous co-simulation method is adopted to analyze the operation characteristics of system integration,which solves the problems of slow simulation speed,poor convergence and low simulation accuracy inherent in complex large-scale system simulation.Based on the distributed heterogeneous co-simulation technology,the virtual simulation test on system level can be carried out to comprehensively cover the requirements of working conditions,and the rapid verification and iteration of the system can be realized.The feasibility of the mode is verified by the virtual simulation test of the coupling characteristics between EHA and power system of more electric aircraft.
