汽车整车振动特性研究综述

综述了汽车整车振动特性的研究进展，从振动的角度看，汽车振动系统可分为车自振动系统和动力传动系扭转振动系统，在汽车车身振动特性的研究方面，许多学者对此进行了有益的探索研究，并取得了一定的进展，目前对动力传动系扭转振动特性研究主要采用试验模态分析和有限元等研究方法，建立了较为理想的动力传动系振动分析模型，但限于分析条件，对汽车车身振动和动力传动系扭转振动耦合的研究尚不十分完整，尤其在国内，这一研究尚处于起步阶段，因此，在汽车车身振动和动力传动系扭动振动特性的研究相对成熟的基础上，汽车车身振动力和动力传动系扭转振动的耦合对汽车整车振动特性影响的研究将是今后一段时间的的主要研究内容。

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.
