Embodiment Construction

[0049] Below in conjunction with example the technical scheme of the present invention is described in detail:

[0050] Please refer to Figure 1 to Figure 3 As shown, the dynamic and static goniometer with high-performance structure of the present invention is composed of one or more groups of long-gauge-length strain sensing units 1 distributed in parallel on the base plate 2 and packaged as a whole. The long gauge strain sensing unit 1 is composed of a long gauge strain sensor capable of responding to the characteristic value of the average strain change within the gauge length, such as a long gauge optical fiber or carbon fiber strain sensor.

[0051] Please refer to Figure 1 to Figure 3 and combine Figure 4 As shown, the high-performance structural dynamic and static goniometer of the present invention can be installed on each component to be measured by pre-embedding or fully pasted or pasted at both ends. The number of long gauge strain sensing units 1 included in e...

Abstract

A high-performance structural dynamic state and static state torque angle instrument is formed by distributing one set or multiple sets of long scale distance strain sensing units on a bottom plate in parallel and carrying out encapsulation as a whole. The high-performance structural dynamic state and static state torque angle instrument can be arranged on each component to be measured by adopting the mode of pre-burying, comprehensive pasting or two-end pasting, and the number of the long scale distance strain sensing units contained in each component to be measured is determined according to measuring requirements and onsite conditions. The high-performance structural dynamic state and static state torque angle instrument and measuring method thereof can achieve the sensing of real-time torque angle changing within a large range, and achieve structural elastic-plastic analysis to achieve the purpose of evaluating structural safety performance.

Description

technical field [0001] The invention relates to a technology for health detection and monitoring in civil traffic structures, in particular to a high-performance structural dynamic and static angle sensor based on distributed strain sensing and a measurement method thereof. Background technique [0002] With the rapid development of my country's infrastructure, structural health monitoring systems and related technologies are being widely used in major or complex structures of civil engineering. Flexural members are one of the common members in engineering structures, and the rotation angle is an important index to evaluate its safety performance. At present, the commonly used angle measuring instruments include theodolite, level, attitude meter and electrolyte inclinometer. However, these instruments are not suitable for continuous dynamic monitoring or large-scale multi-point measurement due to the influence of the swing frequency, stability and measurement cost of the se...
