摘　　要：为了降低研究用飞行模拟器重构难度和成本,分析了模拟器最常发生的变更并进行了系统设计.采用面向对象方法构建了系统框架,使用中介者模式和外观模式将飞机模型划分成多个独立、界面清晰的系统模型.根据座舱面板硬件特点提出了基于CAN总线的一对一分布式采集系统,采用层次化策略减少了采集盒与座舱面板的耦合.设计了737系列研究型模拟器并展示了具体实现.应用结果表明,通过现有软件和硬件的复用能够有效减小飞行模拟器变更难度.Software and hardware of a research flight simulator,which is an important aeronautic experiment device,need to be reconfigured depending on the purpose of the experiment.To reduce the complexity and cost of the reconfiguration,common changes of the flight simulator were analyzed and a system design was given.The design of the software architecture for a reconfigurable flight simulator with object-oriented design principles was discussed,and mediator and facade patterns were adopted to make the system model clear and independent.A one-to-one distributed data acquisition system based on CAN bus and hierarchical division strategy was proposed in order to decouple the panels along with the data acquisition system.The research flight simulator from the Boeing 737 series was designed and shown.Application outcomes indicate that reuse of the software and hardware can save cost and time for changing the subsystem of a flight simulator.
