Abstract:
Iranian researchers from Amirkabir University of Technology presented a mathematical model to predict vibrating behavior of conical shell's nanocomposite objects.
Results of the research have applications in aerospace, oil and gas industries.
Composite pieces of conical shell are used in novel industries such as aerospace and mechanics as structural components. In some applications, the pieces are imposed to rotation at constant angular velocity. It is not impossible to observe changes in their vibrating properties due to the initial stresses caused by eccentricity and Coriolis forces. Therefore, it is essential to precisely evaluate vibrating properties of the pieces at operational conditions during their designing and production.
This research studies the vibration of compounds strengthened with carbon nanotubes in circular conical shells. The researchers studied different arrangements of nanotubes and the effects of Coriolis forces on the frequency of circular shells. In fact, efforts have been made to present a mathematical method by studying Coriolis effects in structures with very high rotating speed.
Rotating systems and their vibrations can be predicted by using the modeling, and their responses can be modified. This fact results in an increase in efficiency, low density, high strength and long lifetime of the structures.
Results of the research have been published in Composite Structures, vol. 117, issue 1, 2014, pp. 187-200.
