Flow-Informed Vibration-Based Health Monitoring Technique

What is it about?

We present a structural health monitoring (SHM) technique that detects the type and extent of the damage in the presence of variable environmental conditions. The model is tested with virtual simulations, where the flow-induced vibration data collected through the sensor is used to determine the system properties and damage extent. It is shown that the proposed two-stage optimization method is robust to the environmental effects and can be used for high-speed applications.

Why is it important?

Traditional structural health monitoring (SHM) techniques are often based on the assumption that the loading is either absent or can be treated as a stationary random variable. Many of the current SHM methods also necessitate strong actuation or an excessive number of sensors unsuitable for high-speed applications. The proposed method requires no artificial actuation and can be applied on-the-fly.
