Abstract
A turbocharger 51 is provided with an improved bearing 52, which may be formed as a semi-floating as a semi-floating ring journal bearing which has hydrodynamic tilting pads 53 on the inner diameter thereof and compliant structural dampers 54 on the outer diameter thereof. The compliant structural dampers 54 are installed between an outer bearing surface and an inner surface of a bearing chamber 56. These compliant structural dampers 54 can be formed as metal mesh dampers 71 or bump foil dampers 72 which are effective to dissipate mechanical energy from structural damping and dry-friction.
