摘要： A vibration damper includes a hub, a first mass, a first resilient coupling, a second mass, and a second resilient coupling. The first mass is disposed concentrically about the hub. The first resilient coupling resiliently couples the first mass to the hub. The first resilient coupling has a first spring constant. The second mass is disposed concentrically about the first mass. The second resilient coupling resiliently couples the second mass directly to the first mass. The second resilient coupling has a second spring constant that is less than the first spring constant. The first mass and the first resilient coupling are configured to attenuate vibration at a first frequency. The second mass and the second resilient coupling are configured to attenuate vibration at a second frequency. The second frequency is lower than the first frequency.

摘要： In a digital image registration method, a second digital image is transformed to be more like a first digital image using a modification function, resulting in a modified second digital image. A set of first features of each of the first and modified second digital images is determined. Zones are specified in each of the first and modified second digital images. A set of zonal features, of each of the zones is determined. Compound mutual information is computed from the first and zonal features. The modification function is altered. The transforming, determining, specifying, determining, computing, and altering are iterated until the compound mutual information is maximized.

摘要： A propshaft assembly includes a shaft structure having a hollow cavity and an insert member being positioned within the hollow cavity and engaging the shaft structure. The shaft structure vibrates in response to receipt of an input of a predetermined frequency such that a shell mode anti-node is generated. The insert member is located at a position that approximately corresponds to the anti-node and has a compressive strength that is tailored to an anticipated displacement of the anti-node to thereby attenuate vibration of the shaft structure.

摘要： A method for determining 3D distances on a 2D pixelized image of a part or object includes acquiring a real 2D pixelized image of the object, creating a simulated image of the object using the 3D CAD model and the 2D pixelized image, determining a specified cost function comparing the simulated image with the real 2D pixilated image and repositioning the simulated image in accordance with iterated adjustments of a relative position between the CAD model and the 2D pixilated image to change the simulated image until the specified cost function is below a specified value. Then, the workstation is used to generate a 3D distance scale matrix using the repositioned simulated image, and to measure and display distances between selected pixels on a surface of the real image using 2D distances on the 2D pixelized image of the object and the 3D distance scale matrix.
