摘　　要：对铝合金航天结构件受载情况下端框铆接缝隙变化测量进行研究,搭载静力试验模拟航天器飞行过程中的典型最严酷的载荷环境,采用三维数字相关技术进行测试某铆接界面缝隙变形情况,并将三维数字相关技术测量数据与塞尺进行对比,试验数据表明:三维数字相关技术用于缝隙测量,精度高,且测量可实现实时监测。In this paper, the aperture change of the aluminum alloy aerospace structural parts under real load is researched. Static tests are carried out to simulate the load environment of flight course. Test results prove that, compared with the traditional methods, 3D digital speckle correlation method has good adaptability and precision on aperture change measurement, and it can accomplish non-contact, real-time measurement on 3D deformation or stress concentration.
