Journal bearings vibration analysis in condition of a low lubrication

Om Prakash Yadav

You can chose any system with clearance and or friction discontinuity. Discontinuities introduce nonlinearity.

Possible areas to work are:

- Nonlinear dynamic analysis of any mechanism considering joint clearances.

- Nonlinear vibration and control to improve accuracy of machine tool

- Take a nonlinear suspension and perform vertical dynamics using this suspension on a bike or car model.

If you want to further discuss anything; you are welcome.
