| Abstract | This paper presents a numerical treatment to effectively calculate the static characteristics of the full tilting-pad gas bearings by means of the finite element method. The dimensionless results obtained by analyzing the full three-pad tilting-pad bearings cover the eccentricity ratios from 0.0 to 0.95, the bearing preload coefficient from 0 to 0.4, the bearing number from 0.1 to 4.0 and the bearing length-to-diameter ratios from 0.8 to 2.0. Simultaneously, the results under different eccentricity ratios are compared with those of the previous references to confirm that the treatment is effective to predict the static performances of this kind of bearings. The numerical results indicate that these parameters of the bearing all have very pronounced effect on the static performances of this type of bearings. With these parameters increasing, the load capacity of the bearings and the friction between the surface of the journal and the bearing become larger, and other coefficients also change. That is to say, the static performances of the bearings could be enhanced by change these parameters. The results could be extended analytically to more bearings with similar sizes and aspect ratios. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
