摘　　要：针对太阳能面板日常清洁困难且效率低的问题,设计了一种太阳能面板清扫系统,并对其自动卸尘机构进行了优化设计.首先,通过Solid Works建立了太阳能面板清扫系统的三维模型,并将系统中的自动卸尘机构分解为摆动导杆机构和摇杆滑块机构;然后,利用解析法建立自动卸尘机构数学模型,通过MATLAB得出滑块的位移、速度以及加速度等运动参数的图形化求解;最后,使用ADAMS建立自动卸尘机构的运动学模型,对其进行运动学分析,并以滑块的最大压力角和运行加速度最小为目标函数对自动卸尘机构进行优化设计.结果表明:滑块的最大压力角经优化后减小了58%,加速度变化范围减小了12.058%;通过优化设计,自动卸尘机构的结构更加合理紧凑,为进一步研究太阳能面板清扫系统提供了参考依据.Abstract： Aiming at the difficulties in cleaning solar panel and its low mechanical transmission efficiency, a solar panel cleaning system is designed and the optimal design is performed on its automatic dust release mechanism. Firstly, the 3D model of the solar panel cleaning system was established by using SolidWorks, and the automatic dust release mechanism was divided into oscillating guard bar mechanism and rocker-slider mechanism. Secondly, its mathematical model was established and analyzed by using analytical method. Graphical solution of motion parameters, including displacement, speed and acceleration of the slider, was obtained by using MATLAB software. Finally, Kinematics model of the automatic dust release mechanism was established by using ADAMS, and kinematics analysis was performed. Taking the minimized pressure angle and acceleration of the slider as the objective function, the optimal design of automatic dust release mechanism was achieved. It is found that the maximum pressure angle was reduced with a rate of 58 %, and the range of acceleration was reduced with a rate of 12.058 %. The optimization effect is obvious, which has a certain guiding significance for the further study of solar panel cleaning system.
