高超声速巡航飞行器动力学虚拟样机设计

Dynamic Virtual Prototype Design of Hypersonic Cruise Vehicle

在研制物理样机之前建立动力学虚拟样机,可以对已有的方案进行论证、对产品进行测试和评估以及全系统的合成仿真,能够有效的缩短研制周期和节约研制经费。详细划分了高超声速巡航飞行器动力学虚拟样机系统的层次结构,建立了样机子系统数学模型,并以此为基础,应用模块化设计思想,在仿真平台上实现了虚拟样机系统及其子系统的样机仿真模型设计。使用现有的高超声速巡航飞行器的总体方案对虚拟样机系统进行了仿真验证,通过对结果的比较分析可以得出,样机系统设计合理,将为高超声速巡航飞行器的研制提供重要技术支持。

Due to the complexity of the hypersonic cruise vehicle, it is desirable to build a virtual prototype system of hypersonic cruise vehicle before building the physical prototype system, thus, it can shorten development cycle, and economize development fee. This paper analyzes the library structure of the virtual prototype system, and finishes the building of the prototype frame system, and completes the implementation of dynamics prototype on VPM （ Virtual Prototype and Modeling）. Finally, the virtual prototype , validated by using given overall project of a hypersonic cruise vehicle, will support the design of the hypersonic cruise vehicle.
