  4. Abstract:
  5. In this article a novel method has been developed to improve the ride comfort of a passenger car by optimum choice of shock absorbers. The objective is to minimize the fatigue provided in the body due to transmitted vibrations. A comprehensive ADAMS model of the car was constructed for perfect simulation of car motions in different maneuvers. This model was validated by further construction of a car and test rig model, and comparing hydro-pulse test data on the real car with simulation results of ADAMS model. The real road profile was adopted as stimulus for the model. Copyright © 2005 SAE International
