摘要
针对PK型多楔带,采用轴向运动梁模型建立了PK型工业多楔带横向振动的数学模型,利用Runge-Kutta法求解了带的横向振动位移曲线,研究了主动轮转速和张紧力对横向振动的影响规律,基于刚柔耦合技术,利用多体动力学分析软件Recur Dyn建立了PK型多楔带的横向振动仿真模型,通过仿真得到带轮紧边中点处的振动曲线,验证了所建立的横向振动方程的准确性和可靠性,为基于减振降噪要求的工业多楔带设计提供了一种数字化仿真分析方法。
As far as PK V-ribbed belt is concerned,this paper establishes a mathematical model of transverse vibration by using the axial moving beam model,which uses Runge-Kutta to solve the transverse vibration displacement curve and studies the influences of the rotational speed of driving wheel and the tension force on the lateral vibration. Based on rigid-flexible coupling technology,it establishes a simulation model of PK V- ribbed belt transverse vibration by using the multi-body dynamics analysis software Recur Dyn.Through simulation,the vibration curves of the belt wheel at the midpoint are obtained,and the accuracy and reliability of the lateral vibration equation are verified,providing a digital simulation analysis method for vibration and noise reduction-based V-ribbed belt design.
