From the rolling contact problem of two viscoelastic cylinders with parallel axis, a series of normal-tangent contact coupled integration equation is obtained.
从两个平行轴粘弹性圆柱体的接触问题出发，可以得到一个法向接触和切向接触耦合的积分方程组。
Tangent track, on the other hand, may be ground to several contact points to promote non-conformal contact and thus reduce wheelset hunting.
与之对应，直线段的钢轨通常打磨成与车轮有几点接触的形状，车轮与轨道之间是非共形接触，从而减少轮对不正常的摆动。
The contact Angle is the Angle between the tangent line at the contact point and the horizontal line of the solid surface.
接触角是角之间的切线的联络点和水平线的固体表面。
