独立旋转车轮导向机理研究

Research on Guiding Principle of Independent Rotating Wheels

讨论了对导向产生影响的轮轨作用力;比较分析了传统轮对和独立旋转车轮的导向机理。结果表明传统轮对虽存在蛇行运动,但具有较好的导向性能;独立旋转车轮不存在蛇行运动,但其直线上自动对中性能和曲线上的导向性能不如传统轮对。

This paper discusses the contact force between wheels and track and compares the difference between the guiding principle of independently rotating wheels and that of traditional wheelsets. The results show that the traditional wheelsets has automatic guiding performance despite of hunting movement and independent rotating wheels has no hunting movement, but its performance of self rurming back to center on straight line and guiding on the curve is not as good as that of traditional wheelsets.
