y of 0.25 Hz. Figures 10 2 Hz respectively. and 11 show that steering wheel command angle, b) Frequency Response. denoted by ANGSW, is followed closely by pinion This task has been achieved in the f ollowing steps: angle, denoted by ANGPN. In addition, the power 1. Perform transient response for e ach of the following piston differential pressure, denoted by DPPP, has cases defined by tire high s pot frequency or vehicle correct amplitude and frequency. D PPP waveform speed: does not show any sign of the steering shudder.
