【摘要】：研究含有单向离合器以及张紧轮的轮-带传动系统的稳定稳态周期响应。建立含有单向离合装置的,由主、从动轮、张紧轮、张紧器以及多楔带组成的三轮-带动力学模型。该模型中,滑轮和附件轴间通过单向离合器传递扭矩。考虑带的轴向弹性刚度以及各轮轴处阻尼的作用,建立三轮耦合、分段连续的控制方程。采用谐波平衡法分析轮-带系统在简谐激励下的耦合非线性振动的稳定稳态响应。通过比较有无单向离合装置的系统稳定稳态幅频响应曲线,研究单向离合装置对轮-带传动系统非线性动态特性的影响。并运用Runge-Kutta方法直接数值求解系统的时间历程,进而对比验证基于谐波平衡法得到的稳态响应分析结果。
[Abstract]:The steady periodic response of a pulley belt transmission system with a unidirectional clutch and a tensioning wheel is studied. A three-wheeled belt dynamic model consisting of main, slave pulley, tensioner and multi-wedge belt with unidirectional clutch is established. In this model, the torque between pulley and accessory shaft is transmitted through one-way clutch. Considering the axial elastic stiffness of the belt and the damping of each axle, the governing equations of three-wheeled coupling and piecewise continuous are established. The harmonic balance method is used to analyze the steady state response of coupled nonlinear vibration of wheel-belt system under simple harmonic excitation. The influence of unidirectional clutch on the nonlinear dynamic characteristics of wheel-belt transmission system is studied by comparing the steady state amplitude-frequency response curves of the system with or without unidirectional clutch device. The Runge-Kutta method is used to solve the time history of the system directly, and the steady-state response analysis results based on harmonic balance method are compared and verified.
