Rotordynamics of automotive turbochargers is dealt with in this book
encompassing the widely working field of small turbomachines under real
operating conditions at the very high rotor speeds up to 300000 rpm.
The broadly interdisciplinary field of turbocharger rotordynamics
involves
1) Thermodynamics and Turbo-Matching of Turbochargers
2) Dynamics of Turbomachinery
3) Stability Analysis of Linear Rotordynamics with the Eigenvalue
Theory
4) Stability Analysis of Nonlinear Rotordynamics with the Bifurcation
Theory
5) Bearing Dynamics of the Oil Film using the Two-Phase Reynolds
Equation
6) Computation of Nonlinear Responses of a Turbocharger Rotor
7) Aero and Vibroacoustics of Turbochargers
8) Shop and Trim Balancing at Two Planes of the Rotor
9) Tribology of the Bearing Surface Roughness
10) Design of Turbocharger Platforms using the Similarity Laws
The rotor response of an automotive turbocharger at high rotor speeds is
studied analytically, computationally, and experimentally. Due to the
nonlinear characteristics of the oil-film bearings, some nonlinear
responses of the rotor besides the harmonic response 1X, such as oil
whirl, oil whip, and modulated frequencies occur in Waterfall diagram.
Additionally, the influences of the surface roughness and oil
characteristics on the rotor behavior, friction, and wear are discussed.
This book is written by an industrial R&D expert with many years of
experience in the automotive and turbocharger industries. The all-in-one
book of turbochargers is intended for scientific and engineering
researchers, practitioners working in the rotordynamics field of
automotive turbochargers, and graduate students in applied physics and
mechanical engineering.
