Structure Health Monitoring
All structures, including bridges, wind turbines, tall buildings, monuments and historical buildings, water, gas and oil pipelines, tunnels, oil platforms, rails, as well as ships, planes, trains, are exposed to various internal and external forces and conditions. which may cause depreciation, breakdown or weakening of their performance. This failure can occur due to poor or improper construction, lack of quality control, or an acute condition caused by an accident or excessive environmental forces.
In order to be able to observe these destructive changes in the structures and react appropriately before causing serious damage, it is necessary to identify the damage earlier and take maintenance measures to prevent serious damage to the structure and incurring excessive implementation costs. did Monitoring the health of structures provides the necessary solution for the mentioned cases. Health monitoring can be done periodically or permanently installed on the structure. For this purpose, the vibrations or strain in the structure should be measured using appropriate accelerometers or strain gauges installed in specific points of the structure, and then these measurements should be recorded and stored by the signal analyzer. The main activity is the analysis of received information, which is performed by experts in this field using health monitoring software such as ARTeMIS or ME’scope.
The network accelerometer and the miniature accelerometer made by the DidePardazSaba company can be installed as many times as desired on the desired structure and measure the vibrations of the structure synchronously at different points by the vibration analyzer (DPS_DAQ). If it is not possible to wire between the sensors in some equipment, a wireless accelerometer or strain gauge can be used.
