Design of Combined Load Bearing System of Static Test for Full-Scale Cylinder of Fuselage

为快速完成试验承载系统准备,提出了专/通用设备混合使用的框架-立柱组合方案。设计了一体化承载框架及检查平台、前端承载分系统、后端承载分系统,形成了组合式承载系统,并对关键结构进行了有限元分析和试验验证。结果表明,该承载系统强度及功能满足试验要求。通用设备的使用有效提高了试验效率,降低了试验成本。

In order to prepare the load bearing system of static test quickly,a frame-column scheme combined with special and general equipment is put forward.The integrated load bearing frame and inspection platform,the front load bearing subsystem and the rear load bearing subsystem are designed,which composed a combined load bearing system.The key structures are analyzed and tested by finite element method.The results show that the strength and function of the load bearing system meet the test requirements,and the use of general equipment effectively improves the test efficiency and reduces the test cost.
