摘要建立了考虑带弯曲刚度的多楔带附件驱动（Serpentine Belt Accessory Drive，简称SBAD）系统梁耦合振动模型。以某三带轮SBAD系统为对象，计算分析带拉伸刚度、弯曲刚度、带线密度对带段横向振动、带动张力和张紧臂摆角等振动性能的影响；以上述振动性能构建目标函数，以带拉伸刚度、张紧器弹簧刚度和张紧臂长为设计变量对SBAD系统进行优化；最后在以上优化结果的基础上，通过降低带弯曲刚度，进一步改进SBAD系统的振动特性。
Abstract： The rotational–transverse vibration coupling model for Serpentine Belt Accessory Drive (SBAD) system is presented in which belt bending stiffness is incorporated. A three pulleys SBAD system is taken as an example. The effects of the longitudinal stiffness, bending stiffness and linear density of the belt on the dynamic characteristics such as the transverse deflections, the tension fluctuation of the belt and the rotation angle of the tensioner arm are investigated. One optimization strategy is proposed and implemented to control the vibration. In the optimization strategy, the belt longitudinal stiffness, tensioner stiffness and tensioner arm length are taken to be design variables, while the transverse deflections of belt, the fluctuation of belt tension and the rotation angle of the tensioner arm are used to define the objective functions. On the basis of the above optimization results, the belt bending stiffness is reduced to further control vibration of the system.
