INVESTIGATION THE DYNAMIC STRESSES OF VIBRATION IN OUTER RACE OF LOW SPEED BALL BEARING Thaker Salih Dawood Faculty of Agriculture and Forestry, University of Duhok, Duhok, Iraq E-Mail: Thakr1960@ ABSTRACT The race ring in vehicle are subjected to sever load acting between the rolling elements and raceways in rolling bearings which develop only small area of contact between the mating members. Large level of stresses is developed on the surface of the rolling elements and raceways. Consequently, although the elemental loading may only be moderate, stresses induced on the surfaces of the rolling elements and raceways are usually large. The determination of deformation and stress distributions due to both static and dynamic loading is essential in the design stage of the raceways. Finite element model of a stress analysis of the ball bearing has been built considering the race ring as a plane stress problem and choosing the 8 = node isentropic quadrilateral element. A computer package Ansys/5.4 for both static and dynamic analysis. The more damping ratio used, the more stabilizing of the stresses with respect to time. Keywords: ball bearing analysis, finite element method, stress analysis methods. INTRODUCTION Wardle and Poon (
