Dynamic System Identification on DBF - Rigid Links ON - Ground Links ON - Loading Beams OFF
|
DOI:10.4231/D3599Z13P
Experiment Type: Large Scale
Description: System Identification Tests conducted in Lehigh University aim identifying DBF's dynamic characteristics, in terms of frequencies and mode shapes. The results will be used to model the frame for control purposes during RTHT.
The tested structure has no loading beams, but rigid links were attached.
Each in-plane and out-of-plane repetitions contain 10 to 20 hammer hits. In-plane tests took 400 seconds, out-of-plane tests took 300 seconds.
In this experiment ICP/PCB sensors are used. The structure is hit with an impact hammer to get the free vibration of the structure. The signal generated by hammer and sensors are collected by a top-of-edge DAQ system with a built-in ICP signal conditioner, VibPilot. Both sensors and DAQ system used for these experiments were non-NEES and are documented in the Documentation. The binary file of the collected data is converted with VibPilot software, SO Analyzer into MATLAB files.
