摘　　要：基于仿真软件AMESim建立了一种7速干式双离合器自动变速器(DCT)传动系统模型,通过AMESim软件接口将模型仿真代码导入Matlab/Simulink,对该DCT传动系统模型进行了验证,并研究了其换挡过程中两个离合器工作时域重叠程度对其换挡品质的影响。结果表明,重叠时间过长会加剧传动系统的振动,增加换挡冲击度;重叠时间过短,则会影响车辆换挡的动力性,不能体现DCT动力换挡的优点。This paper presents a 7 speed dry DCT model built with the advanced modeling software AMESim.The DCT model simulation codes are then exported to Matlab/Simulink with the AMESim software interface block to verify the validity of the DCT model,and examine the influence of overlapping engagement-time of the two clutches on shifting quality of DCT.The results show that excessive long overlapping will aggravate vibration of the transmission system,increase shifting shock;whereas too short overlapping will affect power property of shifting,and can not demonstrate advantage of power shifting of DCT.
