It also gives some Suggestions on the studies of gradient reduced coefficient of traction in long tunnels and the design standard.
最后，本文就长大隧道坡度折减系数的分析及标准本身的研究提出了建议。
The coefficient of friction for static contact is higher than for dynamic contact, so static contact provides better traction.
此时因为静摩擦系数比动摩擦系数高，所以静摩擦的附着力较大。
The higher the normal load, the smaller the effect of the lubricating oil inlet temperature and rolling speed on the traction coefficient.
随着载荷增大，入口油温和滚动速度对拖动系数的影响减小；
Finally, the dynamics of locomotive traction are analyzed, and a disturbance observer is used to estimate adhesion coefficient.
最后，分析了机车牵引动态模型，并且建立了干扰观测器的粘着系数估计系统。
