根据轮轨接触理论,通过调整内轨轨底坡以取得机车车辆通过曲线时,轮轨接触合理的几何匹配,是减缓曲线钢轨侧磨的有效措施之一。 According to the theory of wheel and rail contact, it is one of the effective measures to reduce side rail grinding of curve rail by adjusting the geometry of the inner rail rail to obtain the reasonable geometric matching of wheel-rail contact when the locomotive passes the curve.
