Rotordynamics of Automotive Turbochargers by Hung Nguyen-Schäfer, Hardcover | Indigo Chapters

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 involves1) Thermodynamics and Turbo-Matching of Turbochargers2) Dynamics of Turbomachinery3) Stability Analysis of Linear Rotordynamics with the Eigenvalue Theory4) Stability Analysis of Nonlinear Rotordynamics with the Bifurcation Theory5) Bearing Dynamics of the Oil Film using the Two-Phase Reynolds Equation6) Computation of Nonlinear Responses of a Turbocharger Rotor7) Aero and Vibroacoustics of Turbochargers8) Shop and Trim Balancing at Two Planes of the Rotor9) Tribology of the Bearing Surface Roughness10) Design of Turbocharger Platforms using the Similarity LawsThe 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. | Rotordynamics of Automotive Turbochargers by Hung Nguyen-Schäfer, Hardcover | Indigo Chapters
