| 摘 要： | 以一典型的由驱动轮、从动轮、张紧器和多楔带组成的三轮—带系统为研究对象,并对多楔带传动系统中轮的旋转振动、带的横向振动、张紧臂的摆动角度进行实测。针对三轮—带传动系统轮—带耦合振动,建立相应的数学模型。模型中,将带简化为轴向运动弦线,计算时应用Garlerkin法将带的时间—空间连续方程离散成为时间函数与空间函数之积。计算从动轮旋转角度波动、从动轮—带的滑移率、带段中点的横向振动位移、带横向振动的固有频率,并和试验值进行对比分析。结果表明,计算值与实测值吻合较好,从而计算模型和测试方法的正确性得到验证。该测试方法和计算方法对诸如发动机前端附件驱动系统等复杂的多楔带附件驱动系统动态特性的设计具有参考价值。

| Abstract: | A prototypical serpentine belt drive system,which includes a driving pulley,driven pulleys,one tensioner and belt,is taken as a research example for measuring and calculating the rotational vibration of pulley and belt transverse and tensioner arm motion in serpentine belt drive systems.A model for modeling the prototypical serpentine belt drive system to calculate the vibration of pulley and belt is presented.In the model,the belt is simplified as axially moving string,and the pulley is regarded as rotatio... |
