摘要
电测法作为常见的应力应变测量方法有许多的优点,但也有一些缺点,而数字散斑方法在远距离情况下仍能获得足够的光照度,具有延长散斑计量的距离,保证足够的测量灵敏度等优点.提出了将数字散斑方法与ANSYS计算相结合来检测桥体变形的方法,该方法较其他光学测试方法以及电测法具有较强的实用性和较快的计算速度及较高的精确度.
Electrometric method as common stress strain measurement method has many advantages, but also has many disadvantages. But with digital speckle correlation method, enough illumination can be obtained still in the case of long-range, and the speckle measurement distance is prolonged, and adequate measure- ment sensitivity can be ensured too. This paper presents one method by combining the digital speckle corre- lation method with ANSYS calculation to calculate the deformation of the bridge body, which has higher practicality and high computational speed and accuracy by being compared with other optical test methods and electrometric method.
