Abstract
This paper investigates the concise 1D-FEM models of an open crack in a rotating shaft for quantitative analysis. The parameter of these models have been required to determine experimentally, which was the major drawback of these models. Therefore, in this paper, the decision procedures of the parameters in these models are discussed. The characteristics of the parameters regarding shaft's diameter and depth of crack are investigated by using numerical data obtained from 3D-FEM software. Then, the governing equation of the parameter for one model is deduced in terms of depth of crack. The validity of the decision procedure and the deduced governing equation of the model's parameter is clarified experimentally.
