This research examines how various specimen support
arrangements affect a material's damping characteristics.
The 74 lb. sample studied is cast nickel-aluminum bronze and
measures 19.8 x 13.65 x 1 inches. Using previously documented
Naval Postgraduate School research, desired random vibration
analysis has been verified by impulse hammer techniques.
Input excitation is provided by a combination piezoelectric-electromagnetic
vibration generator system and response is
recorded through the use of piezoelectric accelerometers . The
frequency range studied varies from 100 Hertz to 12,500 Hertz.
The vibration generator is threaded into the specimen and the
accelerometers are attached to the machined surface of the
sample with a cyanoacrylate adhesive. Boundary support
conditions include various: foam, bolted and shock-chord
configurations. |
