Mechanical Analysis and Structural Optimization of the Parabolic Trough Solar Collector

Abstract:

Parabolic trough solar thermal power generation system is always restricted by high drive torque, low thermal efficiency and high investment cost. In this paper, the parabolic trough solar collector in a solar energy application base is taken as the research object and FEM was used to realizing its structural light-weighting design. The structural overall performance is improved to lay a foundation for innovating drive mode and expanding the rotation scope. Beginning of the paper, the wind load characteristic was analyzed and its computational formula was provided the magnitude of wind load was computed; then, the static performance of the solar collector was analyzed by using ANSYS Workbench and the worst working condition of each static characteristic was confirmed to service for the later structural optimization; last, the overall optimization scheme of the solar collector was put forward, the position of the reflectors supporting point and the structure of the solar collectors cantilever was optimized.
