| 摘 要： | 为了解驱动工况下轮对横向稳定性,建立了考虑驱动力矩的简化单轮对动力学模型,针对不同轮轨的黏着特性,研究了弹性定位单轮的横向蛇行稳定性.结果表明:驱动工况下,轮对横向稳定性优于惰行工况,对于弹性定位动力单轮对,当平均蠕滑率为0.8%时,横向非线性临界速度为惰行时的1.1倍;驱动时,轮轨黏着饱和导致轮对摇头力矩减小,有利于横向稳定性,但纵向切向力增加使得横向切向力减小,对轮对横向稳定性不利.

| Abstract: | A simplified dynamic model of single wheelset under traction was established to study its lateral stability.The hunting stability was analyzed on different adhesion conditions between wheel and rail.The results show that a single wheelset has a better lateral stability under traction than under idle running,and that when the average creep is 0.8% the nonlinear critical speed of an elastically positioned single wheelset under traction is 1.1 times of that under idle running.Wheel/rail adhesion saturation res... |
