Finite Element Modelling of a Parabolic Trough Collector for Concentrated Solar Power

Nowadays the design of large-scale structures can be effectively improved by adoption numerical models. Even if experimental tests still play a fundamental role, methodological approach that combines testing and modelling technique significantly improve understanding matter. This, in fact, would result more reliable optimization process, drastically reducing efforts uncertainties towards implementation final product. The present work deals with development finite element model for analysis full-scale prototype an innovative parabolic trough collector. collector is analysed under several load conditions order to evaluate its structural behaviour. Each configuration also numerically reproduced. Moreover, it demonstrated capable reproducing both global (stiffness) local (strain state) behaviour structure. Specifically, comparison between data results show good agreement parameter torsional stiffness. Local strain values are well reproduced high-stressed zone. Thus, used as “virtual tool” designers suitability layout modifications, thereby replacing amount commonly needed and, consequently, time costs. Finally, example potentiality adopted computer-aided engineering shown determine most promising solution increasing stiffness trough, while simultaneously limiting required tests.
