Research on Virtual Simulation Test Technology of More Electric Aircraft Electromechanical System
More electric aircraft has higher requirements for the R&D cycle of electromechanical sys-tem 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 com-prehensive 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 het-erogeneous co-simulation method is adopted to analyze the operation characteristics of system inte-gration,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 comprehen-sively 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.
