摘　　要：根据刮板输送机的实际参数,建立了输送机主传动系统的4自由度非线性振动模型,采用 MATLAB 软件编程求出了振动方程的数值解,并用相图和庞加莱映射的方法分析振动系统随电机激振频率变化的准周期运动和混沌运动现象。结果表明,激振频率靠近固有频率附近,系统的非线性特征越显著,构件易发生损坏。According to the actual parameters of scraper conveyor, this paper establishes 4-DOF non-linear model of vibration, obtains numerical solutions of vibration equations by Matlab software, and by the method of Phase graph and Poincare section, analyzes phenomenon of the vibrating system with periodic motion and chaotic vibrations of exciting frequency. By the results of analysis, non-linearity of the system is more obvious and structural units of the system are destroyed more easily when exciting frequency is adjacent to natural frequency.
