• This paper presents a new method to estimate the power contribution on the grip of the tennis racket, in a multiple input system where the input sources may be coherent with one another. Using multi-dimensional spectral analysis, it is found that the biggest part of the vibration source is generated by stress cn the grip of tennis racket. This analysis is modeled as multiple input/single output system when the stress generating system of the tennis racket is very complicated .The power contribution analysis of the vibration sources and stress on the grip of the tennis racket is proved to be useful for this purpose. Finally, the overall levels for stress on the grip obtained by multi-dimensional spectral analysis are compared with those measured and calculated by the frequency response function approach method.
