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 ,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
In this paper, the research progress of vehicle powertrain vibration is reviewed. From the point of view of vibration, vehicle powertrain can be divided into curved vibrating system and torsional vibrating system. At present, experimental modal analysis and finite element method are used to analyze the flexural vibration characteristics of powertrain Research and establish a more ideal bending vibration analysis model in the power transmission system of torsional vibration research, many scholars have made useful exploration and research, and made some progress but limited to the analysis conditions, the vehicle powertrain bending, torsion Vibration coupling research is not yet perfect, especially in China, this study is still in its infancy. Therefore, in the power transmission system bending, torsional vibration research has been relatively mature, the powertrain bending, torsional vibration coupling its The study of the influence of vibration characteristics will be the main research content for some time in the future
