摘要
针对复杂大型箭体壳段结构静力试验采用电测法获取相关试验数据存在的测点有限以及空间局限性等问题,提出了基于数字散斑相关的光学测量方法,可以有效的获取全场应变,从而指导和修正壳段结构的设计。
Because of the limitation of the measure points' counts and space by strain electrical measuring method in the static experiments of complex large launch vehicle shell structures,the digital speckle correlation method was presented. The full-field strain could be obtained effectively,and the method would guide and modify the design of shell structures.
