STRUCTURE INTEGRITY ANALYSIS FOR SOLAR PARABOLIC TROUGH COLLECTOR BY FEM
Structural integrity analysis of the collector by using finite element software ABAQUS incorporated with genetic optimal algorithms were presented in this paper. The bending and torsion failure models concerning on the optical accuracy were established for the trough collector. The conversion of the wind load into the dead load was acted on the collector. The stress, strain and displacement for the collector under respectively 6th level gale, 8th level gale and 10th level gale were obtained. Detailed FEM investigations on the structural behavior under various load cases (dead load, wind loads for a range of pitching angles of the collector and wind directions) for alternate designs, complex computer modeling and ray tracing were performed to obtain the best possible relationship of optical accuracy and collector cost. The results obtained in this paper are available for reference to the structural optimum design of the trough collector.
