    • A system and method for friction management for managing and controlling an application of a friction modifying agent to an area of contact between a railway wheel and a railway rail over which the wheel is traversing to selectively modify the coefficient of friction at the contact area. The system comprises a sensor for detecting a parameter relating to the operation of the railway train. A controller is responsive to the sensor and controls the application of a friction modifying agent to the rail as a function of the parameter. An applicator is responsive to the controller and applies the friction modifying agent to the area of contact between the railway wheel and rail. The invention also includes a method for railway train friction management for managing and controlling the application of friction modifying agent to an area of contact between railway wheel and railway rail over which the wheel is traversing to selectively modify the coefficient of friction at the contact area. The method comprises sensing a parameter related to the operation of the railway train and applying the friction modifying agent to the area of contact between the railway wheel and rail as a function of the sensed parameter.

    • A system and method for controlling an application of a friction modifying agent to an area of contact between a railway wheel and a railway rail over which the wheel is traversing to selectively modify the coefficient of friction at the contact area. A sensor is used for detecting a parameter relating to the operation of the railway train. A controller is responsive to the sensor for selecting one or more of a plurality of friction modifying agents and controls the application of the agent to the rail as a function of the parameter. An applicator is responsive to the controller and applies the friction modifying agent to the area of contact between the railway wheel and rail. A second application of the agent may be predicated upon the effectiveness of a first application of the agent. The selection of the appropriate agent may include a consideration of a current location of the railway vehicle.
    • 一种用于控制摩擦改进剂应用于铁路车轮与铁路轨道之间的接触区域的系统和方法,车轮横过该区域以选择性地修改接触区域处的摩擦系数。 传感器用于检测与铁路列车的运行相关的参数。 控制器响应于传感器用于选择多个摩擦修改剂中的一个或多个,并根据参数控制代理对轨道的应用。 施加器响应于控制器并将摩擦改进剂施加到铁路车轮和轨道之间的接触区域。 代理人的第二个应用可以基于代理的第一次应用的有效性。 适当代理的选择可以包括对铁路车辆的当前位置的考虑。
