|
摘要
针对输送带承载段的振动问题,在分析振动原因的基础上,建立其振动模型,采用MATLAB对振动的动力学情况进行仿真分析,得出其振动的时域图,并改变输送机的托辊间距、拉紧力及冲击载荷的大小,分别对其影响振动的情况进行分析。本文研究的带式输送机振动规律,可用于解决进料口的振动问题以及为带式输送机的设计优化提供依据。
Aiming at the vibration problem of conveyor belt bearing section, on the basis of analyzing the vibration reason, the vibration model is established, the dynamic situation of vibration is simulated and analyzed by MATLAB,and the time domain diagram of vibration is obtained. The influence of the roller spacing, the tension force and the impact load on the vibration of the conveyer is analyzed respectively by changing the distance between the rollers, the tension force and the impact load of the conveyor. The vibration law of belt conveyor studied in this paper can be used to solve the vibration problem of feed port and provide the basis for the design and optimization of belt conveyor.
