摘　　要：介绍了现有的主要速度摩擦模型。用软件建立摩擦效应的数学模型,得到使用摩擦模型后的整车滑磨功和冲击度,并与原数据进行比较。提出一套新的适合于双离合变速器使用的摩擦模型选择方法,讨论现有模型的不足以及影响摩擦因数的因素。结果表明,应用摩擦模型后得出的冲击度和滑磨功更符合实际工况。Dual-clutch transmission has the advantage of being smooth, and no power when shifting. But using two clutch makes distribution and synthesis of the output torque interruption more com- plex. The increase of the friction surface makes the output torque more effected by the changes of fric- tion coefficient. This paper mainly introduced the exiting speed friction model, using software to es- tablish mathematical models of the friction effect, compared the vehicle slipping power and impact with the friction model or without, and proposed a new suitable friction model selection method for du- al-clutch transmission, providing more theoretical basis for the further research of Dual-clutch Transmission.
