Description

technical field [0001] The invention relates to a test device for detecting the deflection of a pole under force, in particular to a photoelectric pole deflection detection device and a detection method thereof. Background technique [0002] At present, the method of combining theoretical calculation and experimental stress analysis is commonly used to optimize the design of the pole-holding structure. In this experimental stress analysis method, a resistance strain gauge is generally pasted on the member holding the pole, and the strain of the member after being stressed is measured, and the strength value of the member is obtained through conversion. For the overall deflection and stiffness of the pole after being stressed, it can only be obtained by doing model tests. Because the model and prototype of the pole are very different in materials and processing methods, the results of the model test are often quite different from the actual situation, which cannot me...
