摘　　要：太阳能跟踪技术的发展对于太阳能利用的推广具有重要的现实意义。该文设计的凸轮推杆机构具有"单一驱动,双向跟踪"的功能,巧妙地实现了控制单一动力源,同时跟踪太阳方位角和高度角的目的。该文采用穷举法,确定跟踪装置各结构件尺寸,同时借助matlab软件计算出全年每天高度角运动的数据点,并通过COSMOSMotion软件将所有数据点导入,快速仿真出凸轮轮廓线,并且应用SolidWorks三维软件完成了太阳能跟踪装置机械部分设计工作。通过在样机上的实际测试与太阳高度角的理论位置对比得到太阳跟踪机构实际误差精度在7%以内。这种跟踪机构与同类其它产品相比,具有耗能小、可靠性高、抗干扰能力强、易维护等特点,适用于各种小型民用太阳能利用装置。The development of solar tracking technology to promote solar energy utilization is significance. An ingenious mechanism of cam plunger with single drive, dual-axis tracking function for solar tracking was designed in the paper, which achieved tracking solar azimuth and altitude angle at same time by a single driver. Design of solar tracking device was completed using the following methods： exhaustively method was used for determination of device structure size, solar altitude angle data points of per day during one year were calculated by using Matlab, cam contour was simulated by COSMOSMotion software with altitude angel data points inputs, the solid modeling of solar tracking device was completed by application Solidworks. By comparison position of solar altitude angle with practical test of prototype and theory computation, error precision of tracking device was within 7%. Compared with other similar products, the tracking device has features of low energy consumption, high reliability, strong anti-interference ability and easy maintenance and is applicable to various small civilian solar devices.
