刚体运动对云纹干涉法的影响

Influence of rigid body movements on Moire lnterferometry

本文详细讨论了试件在空间六个自由度中产生刚体运动时所形成的云纹图特性，定量地分析了各种刚体运动形式对云纹干涉法的影响。经分析表明：在用云纹干涉法测量变形位移场时，只有当试件绕坐标轴刚体转动时才会影响所测变形位移场。

Specifications of Moire patterns produced by rigid body movements in space of six free degrees are dealt with in detail in this paper. Influences caused by six kinds of rigid body movements on Moire interferometry are studied quantatively. Studies prove that influences are caused only by rigid body rotations, when displacement fields of deformation are measured by means of Moire inferferometry.
