| Research Abstract |
The objective of this research work is to improve the characteristics of small size fluid film bearing spindle by using the optimal design method. In this study, firstly a vibration analysis model of fluid film bearing spindle are made and then the optimum combination of design variables are calculated using the optimal design method. From the results of optimum design, it is found that the influence of tolerance of the bearing groove depth on vibration characteristics and there is danger of contact using the optimal design method without tolerance. Moreover, the experimental verification is conducted and good agreements are seen between the theoretical results and experimental ones.
