“双8字”型无碳小车循迹原理中的几何关系研究

Study on Geometric Relations in the Tracking Process of Double-8-Character Carbon-Free Car

“双8字”型无碳小车的循迹过程没有电子控制设备的参与,完全由机械结构实现,因此各机构的尺寸、形状、安装位置等几何条件对于轨迹有重要影响。以基于蜗轮蜗杆结构的“双8字”型无碳小车为基础,总结其中对轨迹有重要影响的几何关系,得出数学模型,给出控制“双8字”型无碳小车的轨迹的方法,从而能更加科学地根据要求来调整轨迹。

The tracking process of double-8-character carbon-free car is completely realized by mechanical structure without the participation of electronic control equipment,so geometric conditions such as size,shape and installation position of each mechanism have an important impact on the trajectory.The double-8-character type of worm wheel and worm structure is taken as an example to summarize the geometric relationship which has an important impact on the trajectory.The method of controlling the trajectory of the double-8-character type carbon-free car is explored,so that the trajectory can be adjusted more scientifically according to the requirements.
