【摘要】 针对机翼下带外挂飞机挂载组合多、振动分析工作量大及现役飞机更新外挂改装的需求,本文通过机翼/外挂系统模型的固有振动特性分析,试图探索基于混合建模的带外挂飞机的固有振动特性分析技术,即以无外挂飞机的GVT模型与经试验验证的外挂有限元模型为基础,采用自由界面模态综合进行混合建模,完成飞机机翼/外挂系统的固有振动特性分析。本文以机翼/外挂系统模型为例,验证了混合建模技术在机翼/外挂系统固有振动特性分析应用的有效性。更多还原

【Abstract】 For the requirements of the multi-combination of external stores under wing,the large cost of dynamic analysis and the active service aircraft updating and reconstructing stores in this paper,by the application of the wing/store model,we discuss a method based on hybrid-mod- eling to analyze the dynamic characteristics of aircraft with stores,that is,basing on the GVT mod- el of aircraft and the FE model of stores,hybrid-modeled the whole structure by the free-interface mode synthesis method,and then got its dynamic characteristics.A numerical example of the wing/store model is given to show that the hybrid-modeling techniques is feasible in analyzing the dynamic characteristics of aircraft wing/stores system.更多还原
