WebA thin cylindrical shell with general boundary condition and symmetrical ABH profile. The cylindrical shell is composed of a uniform portion with constant thickness h u and length l-l abh , an ABH portion with power-law profiled thickness h ( x ) and length l abh , and damping layers with constant thickness h v , and length l v . WebThe bolted joints considered here were simplified as a series of springs with random features. The vibration equation of the bolted joined cylindrical shell was derived based on Sanders’ thin shell theory. The Monte Carlo simulation and statistical theory were applied to the statistical analysis of mode characteristics of the system. everlast shirts sale
