Induced Unbalance as a Method for Improving the Dynamic Stability of High-Speed Turbochargers
The linear analysis demonstrates that the forward whirling mode of the floating-ring at the compressor end also becomes unstable at the higher turbochar...
Multilobe Floating Ring Bearings for Automotive Turbochargers
A numerical model is developed to evaluate the dynamic behavior of the coupled rotor-bearing system. The resulting run-up simulations have been validate...
Leakage Performance and Rotordynamic Characteristics of Bump Floating Ring Seals for Turbopump
Floating ring seal with bump foil(BFRS) was newly proposed and tested. BFRS which has a thickness of bump (0.076, 0.1 and 0.12 mm) are separately tested for pressuredrops of 3.0, 5.0 and 7.0 MPa and rotor-speed up to 24,800 rpm. The m...
Lock-up characteristics of floating ring seals considering rotor whirling motion
This paper presents a lock-up condition with rotor
Towards robust design optimization of automotive turbocharger rotor-bearing systems
Analysis of a turbocharger rotor-bearing system was subsequently performed, showing a more complex response, consisting of multiple critical speeds and the co-existence of sub-synchronous whirling modes. The effect of the rotor-bearin...
J101023 Rotordynamic Fluid Forces of Floating Ring Seal
A floating ring seal (FRS) has been employed as a noncontact type seal, which seals in high-pressure liquid oxygen (LOX) for the rocket engine turbopump...
