Stability Analysis on Rotor Systems Supported by Self-acting Tilting-pad Gas Bearings with Frequency Effects
bearing-rotor system tilting-pad bearing logarithm attenuation rate
2011/8/4
The recent research on stability of gas bearing-rotor systems still mostly adopts the same method as in oil-lubricated bearing-rotor systems. The dynamic coefficients of gas bearings in the case that ...
Real-time Tire Parameters Observer for Vehicle Dynamics Stability Control
tire longitudinal stiffness cornering stiffness vehicle dynamics stability
2011/8/3
The performance of the vehicle dynamics stability control system(DSC) is dominated by the accurate estimation of tire forces in real-time. The characteristics of tire forces are determined by tire dyn...
