Dynamic models for components considered in the design of a solar concentrator

摘要

In this paper an overview of the mathematical models for different structural components proposed for a solar concentrator assembly are provided. The analysis includes dynamic responses of these structures. In particular, attention has been confined to study modal analysis of rigidized struts, thin film lens, and the inflated supporting torus components. The provided solutions for these components are based on theory of elasto-dynamics. The proposed analytical solution can provide numerical results for natural frequencies, modal damping, and mode shapes for each of the three structural components. The validity of the developed models was verified by comparing some of the computed results with those established for special cases. The developed analytical solutions can be expanded to consider the assembly of these parts in the overall design of the supporting structure for a solar concentrator by dynamic impedance matching among the components.
