When selecting brakeshoe, the dynamic frictioncoefficient must fulfill the request of both brake capability and stability.
选择鼓式制动器摩擦片时，动摩擦系数的选择既要满足制动性能，同时也要满足稳定性。

The composite brakeshoeof cast iron is developed to improve the running speed on existing line. The ceramic particles are used in the brakeshoe to improve the frictioncoefficient.
为提高既有线的运行速度，开发了铸铁合成闸瓦，该闸瓦利用陶瓷粒子来提高摩擦系数。
