    摘要： A system and method are provided to monitor the health of a wind turbine gearbox. The system includes a plurality of sensors coupled to the wind turbine gearbox and a controller coupled to the plurality of sensors. The controller is configured to acquire vibration information from a vibration sensor, acquire a tachometer signal, convert the tachometer signal and the vibration information into a cycle domain signal, and perform an order analysis on the cycle domain signal, the order analysis providing information that identifies potential and actual damage within the wind turbine gearbox.

    摘要： A self-shielded gradient coil assembly for an MR imaging system has inner and outer gradient coil windings disposed in coaxial relationship and defining a hollow annular space therebetween. Inner and outer helical cooling tubes are affixed to the outer and inner surfaces of the inner and outer gradient coil windings, respectively, by a thermally conductive epoxy, and a concrete filler material substantially fills the remaining hollow annular space. The concrete filler material may be poured into the hollow annular space to fill the space, or a pre-formed hollow concrete cylinder may be inserted coaxially into the space, defining remaining inner and outer annular volumes which are then filled with a thermally conductive epoxy bonding together the inner and outer gradient coil windings, the cooling tubes and the hollow concrete cylinder.

    摘要： A locomotive diagnostic system. A first sensor outputs a measurement of a first state variable (such as vibration) of a first locomotive component, such as a blower fan bearing set, and a second sensor outputs a measurement of a second state variable (such as rotational speed) of a second locomotive component, such as a blower fan shaft. The first state variable is indicative of the operation of the first component and is dependent on the second state variable. Data represents, for each of a number of different values of the second state variable, first, second, and third ranges of values of the first state variable which indicate, respectively, normal, worn, and failed operation of the first component. A mechanism, such as a digital computer, determines if the measurement of the first state variable is within the first, second, or third range of values of the first state variable for the measurement of the second state variable.

    摘要： A reinforced motor for reducing amplitude of operational vibrations includes a stator having an open end, a rotor disposed through and centrally of the stator and having at least one end, an end shield mounted to the open end of the stator and having an outer surface and rotatably supporting the rotor at the one end thereof, and an elongated stiffening member attached to or formed on the outer surface of the end shield so as to increase stiffness and reduce bending of the end shield and thereby reduce amplitude of operational vibrations produced by rotation of the rotor relative to the stator. A peripheral portion of the end shield forms an opening for receiving a switch housing. The stiffening member is attached on the outer surface of the end shield adjacent to the switch housing opening.
