Abstract | In view of thermal resistance problem of the motorized spindle system, this paper proposes a thermal resistance network model of spindle-bearing-bearing pedestal based on the fractal and Hertz contact theory. According to this model and Kirchhoff’s law, the heat balance equations for thermal nodes are established and solved with Gauss-Seidel iterative method to gain temperature values of the main thermal nodes. In order to accurately understand thermal characteristics of the motorized spindle system, the effect of thermal contact resistance and thermal-conduction resistance is taken into consideration. Thermal simulation analysis is carried out on the motorized spindle system. On a precision horizontal machining center, the temperature rise of motorized spindle parts is implemented under different rotational speeds with LMS data acquisition system. It is shown that temperature values based on thermal resistance network model agree well with those of simulation analysis and experimental results. What is more, the whole thermal deformations of the main components of the motorized spindle system are analyzed. |

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.
