摘要

为了克服传统的变形测量方法的局限性

实现整体变形和测量范围内各点在任一时刻具体位移的全面测量

以得到完整的变形数据

本文采用数字相关散斑法(DSCM)对变形进行了精确测量。首先

通过与传统变形测量方法进行比较

归纳出DSCM具有非接触、精度高、操作简单灵活、测量全面等优点。然后

描述了散斑法的基本理论

建立了相关的数学模型

并根据相关理论开发了相应的测量分析软件XJTUDIC。利用该软件结合相应的硬件设备

对具体的拉伸变形过程进行了测量试验

并将结果与使用引伸计的传统测量方法进行了比较。得到的结果显示两种测量方法的误差在0.2%之内

验证了该方法及相应软件和硬件的可靠性及可行性

为变形的全面精确测量提供了一种有效的工具。

Abstract

To overcome the limitations of traditional deformation measurement methods and complete the comprehensive measurements of the general deformation and the various point displacements within a measurement scope in any time

the Digital Speckle Correlation Method(DSCM) was used in accurate deformation measurement. Firstly

by comparison with traditional methods

it summarized the advantages of the method in non-contact

high precision

simple and flexible operation

overall measuring and so on. And then the principles of the DSCM were elaborated on the five aspects

the relevant mathematical models were established and the corresponding measurement and analysis software XJTUDIC was developed. By using this software with the relevant hardware devices

a tensile deformation process was tested and obtained results were compared with that of traditional measurement method using an extensometer. Obtained results indicate that the error is within 0.2%

which fully validates that the method and corresponding software and hardware are reliability and feasibility and it provides an effective and reliable tool for the precise and comprehensive deformation measurement.
