摘　　要：为研究传动带在运转过程中的非线性振动问题,建立了一套平带传动实验系统.通过多功能控制卡输出的电压模拟量控制伺服电机控制器驱动电机转动,进而产生带的传动.利用激光位移传感器及LKNavigator软件采集并保存带传动过程中的横向振动位移.选取平带系统在匀速转动和有激励扰动的情况下进行多组实验,实验数据的分析证明带在传动过程中存在周期、倍周期、混沌等非线性现象.This paper presented a flat-beh transmission experimental system in order to investigate the nonlinear vibration during belt transmission. The servo controller drives a motor to produce the belt transmission, whose revolving speed is determined by output analog voltage of a multifunctional control card. A laser displacement sen-or and LK-Navigator software were used to measure the transverse vibration displacement. Experiments were conducted in some different speed conditions, including the uniform rotation and parametric excitation. The measured results from experiments verified the existence of nonlinear phenomena
