Analysis of Vibration Characteristics in the Brake Piping System
Published October 03, 2012 by Society of Automotive Engineers of Japan in Japan
There has been a growing need to reduce the levels of unpleasant noise and vibration originating in the braking system. One example of an unpleasant vibration traceable to the braking system is brake shimmy. The resultant vibration gives rise to brake fluid pressure pulsations that are translated into brake torque fluctuations, causing the steering wheel. Accordingly, in order to design an acceptable level of steering wheel vibration, it is necessary to design the brake piping system with suitable vibration characteristics. We have devised a method for calculating the vibration characteristics in which modeling can be done with the four-terminal method using only physical characteristics.
