Abstract: Radius measurement of grid-stiffened cylindrical shell is a significant task for ensuring the welding quality of launch propellant tank. With the widespread adoption of 3-D laser scanning ...

Abstract: This paper is concerned with the dynamic modelling, active vibration controller design and simulation analysis for a cylindrical shell equipped with piezoelectric sensors and actuators.

In physics, on seeking for a deeper understanding of a topic we often formulate simple questions which, though not realizable in practice, should be satisfactorily answered. For instance, what exactly ...

For the design of scaled model and similarity prediction of vibration of 300,000m 3 blast furnace gasholder body, based on energy method and discrete stiffening theory, the scaling principle relation ...
