使用模态分析的方法研究平带驱动系统的耦合振动.平带驱动系统是由连续的可模型化为弦线的平带,离散的滑轮和一个张紧臂组成的混合系统.从控制方程推导得到了系统的特征方程.通过数值计算,研究了轴向运动速度和初始张力对系统频率的影响.
The modal method is applied to analyze coupled vibration of belt drive systems. A belt drive system is a hybrid system consisting of continuous belts modeled as strings as well as discrete pulleys and a tensioner arm. The characteristic equation of the system was derived from the governing equation. Numerical results demenstrate the effects of the transport speed and the initial tension on natural frequencies.
