Abstract:

A study was conducted of the effects of internal pressure and media on the vibration of small cylindrical pressure vessels. Utilizing approximate expressions for elastic potential and kinetic energies of the cylinder-fluid system, LaGranges equation was applied and an expression developed for predicting the frequency of vibration as a function of the pressure and density of the fluid for axial wave factors wavelength M OI RL 0.60, thickness ratios TR 0.03 and number of circumferential waves n 2. End conditions are empirically included in the measured zero-pressure frequency . A series of experiments on a small cylinder of the type used as pneumatic power sources on missiles confirmed the predictions over a range of pressure 0-34 MPA, with helium and nitrogen gases. A technique of nondestructive pressure measurements is proposed based on the results of this study.
