Bearing Stiffness Calculation Using MATLAB: Static and Dynamic Models
Static Stiffness Model Based on Hertz Contact Theory
Theoretical Foundation
The static stiffness calculation for bearings relies on Hertz contact theory. The fundamental expression is:
(K=\n 3}{2}ZED^{1.5}(1−\kappa)^{1.5}\cos^3\alpha)
The parameters are defined as follows:
(Z): Number of rolling elements
(E): Elastic modulus
(D): Rolling ...
