Review on research of vibration characteristics of automobile

The article introduces the advances of research of vibration characteristics of automobile.From the view point of vibration,automobile is divided into a body vibration system and powertrain torsional vibration system.Many valuable studies have been made on body vibration.The model of powertrain torsional vibration has been set up and is more satisfactory.The vibration characteristics of powertrain torsional system is studied with experimental model analysis and finite element method.Owing to the restriction of analysis conditions,the studies on the coupled vibration between body vibration and powertrain torsional vibration are not satisfactory,especially in China.Hence,based on the satisfactory studies on the body vibration and powertrain torsional vibration,it is necessary the research on the coupled vibration between body vibration and powertrain torsional vibration.
