Filed:

Aug 17, 2010

Appl. No.:

12/857677

Inventors:

Ken Barnes - Northville MI, US
Stephen Gibson - Farmington Hills MI, US

Assignee:

AVL Test Systems, Inc. - Plymouth MI

International Classification:

G01N 3/02
G01L 1/22

US Classification:

73856, 73862

Abstract:

A wind turbine gearbox test cell includes a cradle and a base mounted to a first support structure. Load devices are interconnected between the cradle and base and are configured to input at least one of thrust, radial and yaw loads to the gearbox through the cradle to a wind turbine gearbox under test. A controller is in communication with the load devices and is programmed to command the load devices to input the at least one of thrust, radial and yaw loads to the gearbox corresponding to a simulated wind turbine gearbox loading event. The test cell includes dynamometers and gearboxes that can be reconfigured based upon the particular wind turbine gearbox under test.

Appl. No.:

8/237454

International Classification:

G01B 5207

US Classification:

33545

Abstract:

A frame has sensors mounted thereon for engaging selected portions of a sand core and generating signals proportional to sensed dimensions of the sand core. A control unit compares the sensor signals with a zero reference dimension and a dimensional tolerance range for each sensed dimension of the sand core and generates an indication of acceptable/unacceptable core dimensions. A computer monitor and/or light panel is activated by the control unit and provides a visual indication for each sensed dimension by means of numeric data, color, directional arrows or distinct illuminated lights of an acceptable/unacceptable and even a marginally acceptable sand core.

International Classification:

G01M 17/007

Abstract:

A dual-purpose dynamometer assembly is disclosed including a dynamometer motor, a chassis dynamometer roll that can be driven by a vehicle wheel, and a powertrain dynamometer shaft that can be driven by a vehicle powertrain. A gearbox is disposed between and rotatably couples the dynamometer motor with the chassis dynamometer roll and the powertrain dynamometer shaft. At least one chamber wall defining a test chamber is disposed between the dynamometer motor on one side and the chassis dynamometer roll and the powertrain dynamometer shaft on the other side such that the dynamometer motor is disposed outside of the test chamber. There is at least one aperture penetrating the chamber wall through which the dynamometer motor is connected to the chassis dynamometer roll and the powertrain dynamometer shaft. Accordingly, the dynamometer motor is isolated from extreme temperatures within the test chamber.
