利用实验方法研究粘弹性传动带的非线性振动.实验装置中的粘弹性传动带是同步带,通过伺服电机进行驱动,当电动机转速在某一恒定值上下变动时,带中的张紧力也会呈现周期性变化.通过改变传动带中张紧力的频率和幅值,得到了粘弹性传动带的频率响应曲线和周期运动、倍周期运动以及混沌运动的波形图和相图.
The nonlinear vibration of an axially moving viscoelastic belt as typical moving continua was experimentally investigated. The belt was driven by two pulleys, whose rotating speed slightly varied around the average speed. With the change of frequency, we obtained the nonlinear characteristic of the motion around the resonance area. Multi-periodic motion and chaotic motion were found.
