摘要
综述了汽车传动系动态设计理论与建模方法的研究进展.目前国内外学者对汽车传动系弯曲振动和扭转振动特性的研究已取得了一定的进展.但限于分析条件,汽车动力传动系弯曲、扭转振动耦合的研究尚不十分完善.运用基于人工神经网络模型的动态设计方法,研究汽车传动系弯曲、扭转振动耦合对整车振动特性的影响将是今后一段时间的主要研究内容.
The article reviews the advances of research on theory of dynamic design and modeling method in automobile powertrain. Many valuable studies have been made on powertrain bending vibration and tor sional vibration. Owing to the restriction of analysis conditions, the studies on the coupled vibration be tween bending vibration and torsional vibration are still to be perfected. Hence, based on the dynamic design method of artificial neural network model, the research focus in the future should be put on the influ ence of the coupled vibration between bending vibration and torsional vibration upon the vibration charac teristics of the automobile.
