Embodiment Construction

[0039] The specific implementation steps of the present invention will be further described below in conjunction with examples.

[0040] The invention is oriented to the structural loading electrical measurement experiment, and aims to realize the real-time monitoring of the sensor state in the structural loading electrical measurement test, control the risk of the test, and improve the success rate of the test. Taking the axial pressure bearing test of a reinforced cylindrical shell with a large opening as an example, the maximum axial pressure of the scheduled test is 40 tons. During the loading process, the electric measuring system needs to be used to measure the strain of the structural part position, and the sensor of the present invention is used for real-time monitoring during the loading process. state.

[0041] In order to achieve the above object, the present invention specifically comprises the following steps:

[0042]Step 1. Sensors are numbered and graded. Dur...

Abstract

The invention provides a real-time sensor state monitoring method for structure loading electric logging tests, belongs to the field of experimental mechanics. The monitoring method comprises the steps of: firstly, numbering and grading sensors before structure loading, carrying out pre-loading, automatically judging sensor abnormities according to measured data and adjusting the sensors by a tester; secondly, carrying out official loading after confirming that the sensor does not need adjustment, calculating linearly dependent coefficients between the measured data of each sensor and load data in real time in the loading process, and analyzing the working state of each sensor; and finally, judging the state grades of the sensors according to real-time working states and importance gradesof the sensors, and adjusting the test progress according to corresponding processing measures. According to the method, the automatic real-time monitoring and alarm for sensor states in structure loading electric logging tests are realized and the test risks can be effectively controlled to improve the test success rate.

Description

technical field [0001] The invention belongs to the field of experimental mechanics, and relates to a real-time monitoring method of sensor state used for structural loading electric measurement test. Background technique [0002] In the loading electrical test of the structure, it is often necessary to arrange a large number of sensors such as strain gauges and displacement gauges on the surface of the structural test piece to measure the strain, displacement and other data of specific parts of the structure. In the test preparation stage, when the sensor fails, it is easy to troubleshoot and repair; however, in the process of the test, once the sensor fails, in the absence of an automatic detection system, it is usually difficult for the test personnel to quickly find and deal with it, which is very likely to cause damage to the experimental data. Lost, affecting the test results and even leading to test failure. Therefore, it is necessary to invent a real-time monitoring...
