The Relationship Between the Parameters of Automobile Supension System and the Response of Vibrational Stress

When the input of the situation of the road is given, the stress response of the automobile suspension system can be defined. The smoothness of the automobile, the intrinsic characteristics of the suspension, the life of the loaded parts and the reliability of the system all have close relationships with the parameters of the system. Taking the independent suspension system as the research object, the relationship between the parameters of suspension system and the response of dynamic and static vibrational stresses and the acceleration of the vehicle have been studied and the sensitivity of the response to the parameters is obtained. Through changing the matching of the parameters, the design of the suspension system can be improved, and this may serve as a basis for the optimization of the parameters .
