Abstract:
The current work aims on determine the operating temperature of hydrodynamic journal bearing by using numerical method. To derive an alternative method to find out the operating temperature of journal bearing.The software using in numerical method is MATLAB Software.The paper introduces some problems of hydrodynamic journal bearing based on Thermo-hydrodynamic Analysis with special attention kept on the calculation of operating temperature of bearing that are based on developed programs of numerical simulation of bearing operation. Numericalmodelling is developed to analyse the bearing for the parameters like L/D ratio, viscosity and speed. When a bearing operates at high speed, the heat generated due to large shearing rates in the lubricant film raises its temperature which lowers the viscosity of the lubricant and in turn affects the performance characteristics. Thermo-hydrodynamic (THD) analysis is therefore carried out to obtain the realistic performance characteristics of the bearing. The average film temperature is also an important aspect is to be analysed during the operationNumerical Analysis is done by taking l/d ratio = 1 , applied load 9KN and speed 3600 r.p.m . Then results obtained by analytical method using Raimondi n Byod chart and numerical method i.e. by MATLAB are compare.
