Elasto-multi-body dynamics of internal combustion engines with thin-shell elastohydrodynamic journal bearings

This thesis describes problems associated with noise and vibration concern in internal combustion engines as the result of a growing trend in the development of modern vehicular engines with high power to light weight ratios. There are a plethora of vibration concerns. These are owed to the increasi...
