RISTurbocharger Nonlinear Response With Engine-Induced Excitations: Predictions and Test Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbochargers (TCs) aid to produce smaller and more fuel-efficient passenger vehicle engines with power outputs comparable to those of large displacement engines. This paper presents further ...
On the Effect of Thermal Energy Transport to the Performance of (Semi) Floating Ring Bearing Systems for Automotive Turbochargers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bearing systems in engine-oil lubricated turbochargers (TCs) must operate reliably over a wide range of shaft speeds and withstand severe axial and radial thermal gradients. An engineered thermal ...
Rotordynamics of Small Turbochargers Supported on Floating Ring Bearings—Highlights in Bearing Analysis and Experimental Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbochargers (TCs) improve performance in internal combustion engines. Due to low production costs, TC assemblies are supported on floating ring bearings (FRBs). TCs show subsynchronous motions ...
Test Response and Nonlinear Analysis of a Turbocharger Supported on Floating Ring Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
