| With the rapid development of industry,modern machine tools and machinery are heading to the trend of high speed and high precision. As one of the most significant support components, journal bearing has the advantage of high bearing capacity, good stability, good vibration resistance, low noise, etc. It is widely applied in every machinery industries. In the recent 20 years, dynamic lubricant bearing technology has a great leap. Types of journal bearings have emerged. With all the different structures of journal bearings, it is necessary to summarize them and take further research on their law of performance. These lows will become effective basis while selecting the structure and designing the bearing.As for different structures of bearing, theoretical analysis model is established and computing method is given in this paper. The accuracy of the computing program is validated through comparison with actual experiment and numerical results in Michael’s authoritative book.Bearing performance is analyzed in various structural and working condition parameters. Comparative analysis is done to identify the scope of application for various structures of bearing which provides theoretical basis for bearing structure selection.The interface interactive computing and analysis software is developed based on VC++. With mixed programming method, VC++ and Fortran is adopted to develop core module of computing, while VC++ and Matlab develops the 3-D image display module, and VC++ and APDL develops the elastic deformation module. The software contains database which storages and accumulates common material parameters.Calculation and analysis for various structures of bearing is summarized and gathered in this paper. The software integrates different function module which is interactively friendly and results expressed intuitively. With the verification and validation of accuracy, the software is competent for helping with actual bearing design. |
