Dynamic analysis on picking process of cotton picker spindle

摘要

摘要: 针对采棉机采棉头核心部件摘锭易磨损、易折断的工程实际问题，根据采摘系统的结构特点和振动特性，建立该系统单自由度干摩擦振动模型，考查摘锭在摩擦力作用下的动力学响应，分析了系统运动中存在的黏滑振动，并通过摘锭速度及结构参数的变化揭示了摘锭在工作过程中实际动力学特性，同时探讨了呈现出的动力学行为对摘锭磨损的影响，并提出抑制摘锭磨损的建议。该文的理论分析与数值结果为采棉机摘锭的结构设计及优化提供参考。

Abstract: In order to resolve engineering practice problems such as cotton picker ingots were easily worn and broken during picking process, under these circumstances, the model of picking systems was built for one- degree-of-freedom dry friction oscillation according to its structural feature and oscillation behavior. Dynamic response of ingots during picking process with friction force was investigated, and the stick-slip vibration of system motion was analyzed. Thus, the actual dynamics characteristic during picking process was summarized by changing speed and structural parameter of ingot. As well, the suggestion was given to decrease the wear degree of cotton picker ingots by studying on the effects of dynamic behavior on ingot wear. The theoretical analysis and numerical results are applicable to the structural design and optimization of cotton picker ingots.
