Noise Testing of Gearboxes and Transmissions Using Low Cost Digital Analysis and Control Techniques 861284

The combination of low cost personal computer, powerful array processor and intelligent data interface make it possible to carry out multichannel noise and vibration analysis at high speed during acceleration of a gearbox on a test rig. Order analysis is used to compare noise signatures with preset targets for up to 20 orders of input shaft rotation. Targets are derived by the computer from practical test results. The computer also controls the test sequence and provides for varying the sequence according to the gearbox to be tested. Design considerations for a Quality Audit system are discussed and practical test results presented.
