THE METHODS OF CALCULATING THE GRAVITY STIFFNESS AND ROLLING RADIUS FOR THE SIMPLIFIED MODEL OF WHEELSET

  • 摘要: 本文用几何方法给出了轮对质心高度和滚动半径与侧向位移之间的函数关系,从而获得这些量的解析表达式;并通过运动学方法,证明了重力刚度和滚动半径直观简便的计算方法是正确的。

     

    Abstract: In this paper, the relationships between the height of the centroid of the wheelset and the rolling radius with the lateral displacement are given by geometric method, so that the analytical expressions for these quantities are obtained. In addition, the simple calculation methods for the gravity stiffness and rolling radius are proved to be correct by kinematic method.
