摘　　要：与固定式安装太阳电池板比较,采用太阳能跟踪系统可使其发电量提高25%~40%。本文根据太阳跟踪器俯仰机构几何关系,建立了完整太阳跟踪过程中电动推杆承受载荷最小的优化设计模型,通过编写MATLAB程序,对俯仰机构的布局参数和机构尺寸进行了优化。算例结果表明,优化的俯仰机构增大了最小传动角,提高了机构的传动性能,降低了电动推杆的载荷,保证了机构性能和可靠性。Compared with a stationary solar panel,a solar tracking system can increase the power generation by 25%~40%.Based on the geometric relationship of pitching mechanisms of a solar tracker,the paper establishes the optimal model of minimum load on an electric linear actuator during its complete solar tracking process.The MATLAB program is used to optimize the process parameters and sizes of the pitching mechanism.The results on numerical examples show that the optimized pitching mechanism increases its minimum transmission angle,improves its transmission performance,reduces the load of the electric pusher and ensures its performance and safety.
