Vibration Transmissibility Experiment

This experiment involved exciting each negative stiffness honeycomb structure with a sinusoidal chirp signal from 5-600 Hz. The transmitted vibration was measured with a laser vibrometre. All measurements in the .mat files are in volts.Some test files were failures with the equipment moving off axis. It is easy to tell which ones these are. Best tests to use for each structure are:Q = 1.67 - use T2Q = 2.00 - use T1Q = 2.31 - use T5Q = 2.71 - use T2The velspec files show the voltage trace. The unnamed figure shows the prelim frequency spectrum - this spectrum needs adjusting.
