This book describes the rotordynamics of automotive turbochargers, which encompasses the analysis of the dynamics of rotating machines at very high speeds. This interdisciplinary field involves 1. thermodynamics and engine processing knowledge to compute working conditions of turbochargers , 2. fluid and bearing dynamics to calculate various operating thrust loads and to design hydrodynamic oil-film bearings and 3. tribology to reduce the bearing friction. Mathematical background in modeling and simulation methods is necessary, but the prerequisites are being kept to a minimum. The book addresses both practitioners working in the field of rotordynamics of automotive turbochargers and graduate students in mechanical engineering.

Acerca del autor

Dr. Hung Nguyen-Schaefer is a senior expert in rotor-dynamics and bearing designs of turbochargers at Bosch Mahle Turbo Systems (BMTS) in Germany. He received his B.Sc. and M.Sc. in mechanical engineering with nonlinear vibrations in fluid mechanics from the University of Karlsruhe, Germany in 1985, and his Ph.D. in nonlinear thermo- and fluid dynamics from the same university. In 1988 he joined Bosch company, and worked as technical manager on many development projects of anti-lock braking and traction systems, high-pressure fuel injection systems, combustion engine systems, fluid cavitation, and electric turbochargers for automotive fuel cells (PEMFC). Since 2007 Dr. Nguyen-Schaefer has been in charge of rotordynamics and bearing design of automotive turbochargers at BMTS located in Stuttgart, the joint venture of Bosch and Mahle. He has much experience in the fuel injection systems of gasoline, diesel, compressed natural gas (CNG), automotive turbochargers, rotordynamics, and bearing designs.

De la contraportada

This book deals with rotordynamics of automotive turbochargers while encompassing the analysis of the dynamics of rotating machines at very high rotor speeds of 300,000 rpm and above. This interdisciplinary field involves 1. thermodynamics and turbo-matching knowledge to compute working conditions of turbochargers, 2. fluid and bearing dynamics to calculate various operating thrust loads and to design the rotating floating ring bearings (two-oil-film bearings), and 3. tribology to improve the rotor stability and to reduce the bearing friction. Mathematical background in modeling and simulation methods is necessary; however, the prerequisites have been kept to a minimum. The book addresses both practitioners working in the field of rotordynamics of automotive turbochargers and graduate students in mechanical engineering.
