摘要

地面试验是目前验证飞机结构性能和品质最重要的手段，全机地面静强度试验载荷高、变形大，飞机结构有可能发生非预期破坏，试验系统也存在意外故障风险，这些对试验设计与实施带来巨大挑战。对飞机结构静强度虚拟试验技术进行了系统研究，建立了试验物理系统数字化、结构力学行为虚拟化及试验过程虚拟物理融合化技术，形成了物理与虚拟试验双线并行、互动融合新模式。将虚拟试验技术在大型飞机全机静强度试验中进行了应用，飞机变形误差1%，应变误差小于10%，有效提升了全机静力试验的可靠性和安全性，缩短了试验周期，为飞机研制发挥了重要作用。

Abstract

Ground test is currently the most important means to verify the performance and qualities of aircraft. High load and large deformation occur in the ground static strength test of full-scale aircraft, the risks of aircraft structure unanticipated damage and testing system unanticipated breakdown bring great challenges for testing design and its implementation. The virtual testing technique has been investigated, and the digital model of testing system, virtualization of structure mechanical behavior and the physical and virtual fuse of testing process are established, with which the new double parallel and mutual fusion testing modes came into being. The virtual testing technology was successfully applied to the full-scale aircraft static test. Compared with test results, the errors of calculation displacements are less than 1%, and the errors of calculation strains is less than 10%. The virtual testing technology improves the reliability and security of the aircraft static test, and reduces the testing periods, which plays an important role in the aircraft development.

Key words： aircraft structure; static strength; digital design; virtual simulation; interactive fusion
