一种新型2-DOF太阳追踪装置的结构参数优化设计

Optimization Design on Structural Parameters of a New 2-DOF Sun Tracking Device

为提高太阳能装置对太阳能的接收效率,提出一种新型并联机构的太阳跟踪装置。依据位置闭环矢量方程建立该机构的位置逆解模型,推导出速度雅可比矩阵,定义该机构的灵活性能评价指标;绘制太阳追踪装置的任务工作空间,并在其工作空间内给定约束条件,优化得到各参数关系,为该装置的详细结构设计奠定了基础。

To improve the efficiency of solar energy device for solar receiving,a new sun tracking device adopting parallel mechanism was put forward.The kinematics model was established by the position closed-loop vector equation,the velocity Jacobian matrix was deduced,the agency’s flexibility performance evaluation index was defined;the task working space of the sun tracking device was drawn,the relationship between the parameters was optimized by given constraint conditions in its task working space.It lays foundations for the device structure design.
