Thermal model of externally driven spindle: a semi-automatic construction of thermal network
Journal Title: Proceedings in Manufacturing Systems - Year 2018, Vol 13, Issue 1
Abstract
This paper. Focuses on one application to construct a user guided thermal network for externally driven spindle of high speed. The objective is to develop a model the can be used for effective estimation of thermally distribution in a spindle-bearing system using and generator of linear symbolic system of equations that can be solved using a numerically solver in a simpler manner than the tools that use the finite element model. The heat generated by bearings is calculated using a dynamic model of angular contact bearings and cylindrical roller bearings in a distribution and construction that use preload. The results of simulation were compared with similar results from literature and for a moderate level of granulation of thermal network the results were found good for practical applications. The proposed approach is useful especially when we need in a fast manner practical results and the number of node must be find out by multiple iterations with less ore more complex thermal network architecture. The prospective development and further research are discussed.
