Abstract: Various aspects of MSA are presented, including a classification and application scheme. Described are general principles, common to applications of different character. These include data reduction, ...

Abstract: Described is a method of extracting modal deflection patterns by means of acceleration measurements only. This enables the testing of systems/machines under normal operating conditions with many ...

Abstract: This paper describes a scheme for the correction of mass unbalance computations for the effect of torque disturbances. A general approach is dealt with, showing how to assess the disturbance ...

Abstract: This work investigates the accuracy of spectral estimates computed via parametric techniques. Comparisons with results obtained via classical Fourier methods are also presented. The PSD’s (power ...

Abstract: Described is a vibration based diagnostic method aimed at detecting localized defects developing in roller/ball bearings. The signature is decomposed into generalized periodic functions and a ...

Abstract: A unified nearest neighbor-time series analysis approach to the problem of the classification of faults in rotating machinery is developed. The procedure has an optimum minimum probability of ...

Abstract: This paper investigates the relationship between drill life, the sound, and the drift forces produced by the drilling process. Tests were performed while drilling steel with 38 in. twist drills. ...
