摘 要: 综述了车辆动力传动系振动的研究进展。从振动的角度看,车辆动力传动系可分为弯曲振动系统和扭转振动系统。目前主要采用试验模态分析和有限元等研究方法对动力传动系弯曲振动特性进行研究,建立了较为理想的弯曲振动分析模型。在动力传动系扭转振动的研究方面,许多学者对此进行了有益探索研究,并取得了一定的进展。但限于分析条件,对车辆动力传动系弯曲、扭转振动耦合的研究尚不十分完善,尤其在国内,这一研究尚处于起步阶段。因此,在动力传动系弯曲、扭转振动的研究已相对成熟的基础上,动力传动系的弯曲、扭转振动耦合对其振动特性影响的研究将是今后一段时间的主要研究内容。 The article introduces the advances of research of vibration of vehicle powertrain. From the view point of vibration, powertrain is divided into bending system and torsional system. The vibration characteristics of bending vibration is studied with experimental modal analysis and finite element method .The model of powertrain bending vibration has been set up and is more satisfactory. Many valuable studies have been made on powertrain torsional vibration. Owing to the restriction of analysis conditions , the studies on the coupled vibration between bending vibration and torsional vibration are not satisfactory, expecially in china .Hence, based on the satisfactory studies on the powertrain bending vibration and torsional vibration, it is necessary to research on the coupled vibration between bending vibration and torsional vibration.
