Mobility of a Long Cylindrical Shell

摘要: Results of an experimental and theoretical study the mobility a long, moderately thick‐walled, pipe‐like, cylindrical shell are reported. Experimental data for compared, over wide frequency range not previously investigated, with analytical predictions based on thin‐shell theory. Existing solutions free vibrations thin shells extended to predict vibration response point force that varies sinusoidally time, normal‐mode series solution. Practical convergence is special interest. The pipelike was chosen make this problem more severe since resonances in some ranges very closely spaced. For most study, ends were move laterally, but end cross section restrained maintain circularshape; consequently, treated as 1 = n or beam modes, freely supported 2 lobar modes. Some resonant frequencies also ...
