Movement Simulation and Analysis of Twist Needle in the Tobacco Machine based on MATLAB

从某新开发的烤烟编烟机中的曲针运动特性分析入手,通过对曲针部分的曲柄连杆滑块机构的简化,判断机构运动的特性和极限位置。利用Matlab提供的机构运动仿真分析模块SimMechanics,建立编烟机曲针结构模型,并根据实际情况设置运动仿真的各个参数,并对所要研究的对象进行运动数据的测量,对编烟机曲针的预期运动进行了仿真验证,通过对SimMechanics计算出的数据进行分析,获得了符合预期运动特性的参数,为机构的设计提供了可靠的仿真依据,使设计更加完善。

According simplifying the twist needle＇s slider-crank mechanism in this paper,the mechanism＇s movement characteristics and limit position were studied.The analysis of the twist needle＇s movement characteristics in a new tobacco machine was taken into consideration.This study has made use of Matlab to establish the model of twist needle and set the parameters for the simulation of anticipated movement and has made an analysis through the SimMechanics＇ data,which provides the reliable digital evidence and the instruction for the following design.Meanwhile,it provides a reliable basis to make the design more perfect.
