VIBRATION ANALYSIS OF AXI-SYMMETRIC SHELL BY MODE SUPERPOSITION

In the design of axi-symmetric shell structures (such as large cooling towers, chemical reaction towers, and several kinds of tanks and rocket chambers), it is often necessary to predict their vibration responses to various external forces. The authors first describe the linear vibration response analysis of axi-symmetric shell structures by the well-known finite-element method, and use the results to analyse the problem by mode superposition for the case in which the effect of the possible circumferential non-uniformity in building of cooling towers and large shell structures is taken into consideration. Next they analyse geometrical non-linear (large deflection) vibration which is said to present a problem in thin shell structures, such as rocket chambers, and in the dynamic buckling of cooling towers. Finally, they present examples of numerical calculation and study their validity. Order from BSRA as No. 50,012.
