The basic principles and calculation methods for the correlation dimension and Kolmogorov entropy were introduced. The correlation dimension and Kolmogorov entropy were calculated when the gearbox was under different working conditions. The inherent relevancy between the two in depicting of the running condition of the gearbox was analyzed. The result shows that the correlation dimension and Kolmogorov entropy have a good consistency in the description of working status of gearbox. This conclusion not only provides a good basis for the gearbox running condition judgement and fault diagnosing, but also can provide the experimental basis for the chaotic characteristic parameters selection in state monitoring and fault diagnosing.
