摘要
为了便于实际测量，改进了白光客观散斑方法并与反射全息干涉技术相结合，提出了一种测定曲面三维位移场的实验方法。以扇形薄壁截面梁承受弯扭组合变形为例，给出了位移场的实测结果。经与有限元计算值相比较，证明本文方法是可行的。
An experimental approach is presented with which the 3-D displacement field of the curved surface can be obtained by means of white-light relative objective speckle method and reflecting holographic interferometry. A group of displacement results are obtained which are taken from a thin wall section beam supporting bending and twisting. It is convenient for using this method to adjust measuring sensitivity and its operation is simple.
