The dynamics of high speed rotating machinery plays an important role in the modern world. In the design of complex mechanical components and rotating machines, such as turbines, compressors, electrical machines, centrifuges or machine tool spindles, systematic analysis of dynamic behavior is needed. The dynamics of a rotor can be highly influenced by the design of support bearings, since, the critical speeds and the magnitude of vibration responses are dependent on the stiffness and damping

To have the precise knowledge of the dynamics of rotor-bearing systems, it is very much essential to use the correct values of stiffness and damping coefficients of the support bearings. Hertzian contact theory is used to model the force-deformation relationship, also by using matlab software an attempt is made to find the solutions which will result in various plots
