The load acting on the actively controlled cylindrical shell under a transient pressure pulse propelling a moving mass (gun case) has been experimentally studied.
The concept of using piezoelectric stack and stiffener combination is utilized for damping the tube wall radial and circumferential deforming vibrations, in the correct meeting location timing of the moving mass.
The experiment was carried out by using the same stiffened shell tube of the experimental 14 mm gun tube facility which is used in part 1.
Using single and double stacks is tried at two pressure levels of low-speed modes, which have response frequencies adapted with the used piezoelectric stacks characteristics.
The maximum active damping ratio is occurred at high-pressure level.
The radial circumferential strains are measured by using high-frequency strain gage system in phase with laser beam detection system similar to which used in part 1.
Time resolved strain measurements of the wall response were obtained, and both precursor and transverse hoop strains have been resolved.
A complete comparison had been made between the effect of active controlled and stepped structure cases, which indicate a significant attenuation ratio especially at higher operating pressures.
