Abstract:
This paper presents a mathematical model with five degrees of freedom to determine the stiffness of the automotive wheel bearing. The mathematical model consists of two parts. The first part of the developed software solution to determine the contact stiffness for each rolling elements,while the second part on the basis of contact stiffness determines the stiffness of bearing based on the finite element method. Software solution is developed based on Hertz's contact load and John Harris of the quasi-static equilibrium equations. Contact bearing stiffness matrix is determined for different arrangements of bearings in the support. Mathematical model analyzes the influence of the cornering acceleration ofthe automotive wheel and clearance on the bearnig stiffness. The research in this paper shows that the cornering acceleration of the automotive wheel significantly affects the radial stiffness, while the clerances significantly influence the angular and axial stiffness.
