摘要： Provided herein is a method that includes coupling a support fixture having a hanging strap to a frame of an assembly at a location vertically above a rotatable shaft of the assembly; vertically supporting the shaft with the strap; temporarily mounting a pulling fixture to the frame of the assembly, the pulling fixture having a bowl-shaped body and a hydraulic ram coupled to the bowl-shaped body, the pulling fixture mounted to the frame such that a second end of the bowl-shaped body is coupled to the frame and the hydraulic ram is operably coupled to a bearing of the assembly; and controlling the hydraulic ram to apply coaxial force to the bearing to remove the bearing from the assembly or to install the bearing into the assembly.

摘要： A system and method detect and manage conductive gaps between collector devices onboard vehicles and conductive pathways extending along routes traveled by the vehicles. The collector devices are conductively couplable to the conductive pathways. The system and method respond to a detected drop in an amount of electric current being conducted from the conductive pathway to the collector device of a vehicle with a responsive action prior to or during a subsequent drop in voltage being conducted from the conductive pathway to the collector device.

摘要： A control system includes an interface device having a body extending between a first end and a second end and that provides power to a vehicle system from an external power source. Sensors may be coupled with the interface device and detect sensor data associated with the coupling of the external power source with the interface device. A controller receives the sensor data from the sensors and determines a coupling location at which the external power source is coupled with the interface device. The coupling location may be at a first position between the first end and the second end of the interface device. The controller controls movement of the vehicle system to change the coupling location between the external power source and the interface device from the first position to a second position between the first and second ends of the body.

摘要： A method and system include determining a resonant frequency of a vehicle system operably coupled with an external power source that provides voltage and current to the vehicle system. A first filter extracts a phase or a frequency component from the voltage provided by the external power source to generate a stabilizing voltage component. A second filter extracts a phase or a frequency component from the current provided by the external power source to generate a stabilizing current component. The stabilizing voltage component is out of phase with the stabilizing current component. A control input of a converter device of the vehicle system is determined based on the stabilizing voltage component, the stabilizing current component, and the resonant frequency. The stabilizing voltage component, the stabilizing current component, and the control input are communicated with the converter device to change the resonant frequency of the vehicle system.
