RISA Nonlinear Rotordynamics Model for Automotive Turbochargers Coupled to a Physical Model for A (Semi) Floating Ring Bearing System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Automotive turbochargers (TCs) use an engine oil lubricated bearing system to produce acceptable performance (as per the engine volumetric efficiency) and proven reliability. However, the bearings also cause TC rotordynamic ...
A Thermal Model for a Hybrid Gas Bearing System in Oil-Free Turbochargers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With little drag friction, gas bearings operate at high rotor speed and high temperature and thus enable long operating life along with material damping for mechanical energy dissipation. However, most computational tools ...
A Thermo-Hydrodynamic Model for Thermal Energy Flow Management in A (Semi) Floating Ring Bearing System for Automotive Turbochargers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Oil-engine lubricated turbochargers (TCs) operate at high temperature and must withstand large temperature gradients that produce severe thermomechanical stresses in the TC mechanical components. Thus, an insight into the ...
