移动向上和向下（您可以使用转向限制的运动方向） ，直到车轮触摸红色轴线。

Move it up and down (you can use shift to constrain the movement direction) until the wheels touch the red axis.

应用MATLAB的优化工具箱对设计模型进行了优化求解，给出了针对任意一轴线上转向机构的MATLAB优化程序。

The authors used MATLAB optimization toolbox to solve this optimization problem and programmed the solving procedure according to random axle.

于是，与前轮相连的转向节臂使车轮在其轴线上左右转动。

The steering-knuckle ARM, attached to the front wheels, are therefore forced to swing the wheels to the right or left on their pivots.
