Optimization Design of Cylinder Double-linkage Double Crank in Speed-change Mechanism of Comber

通过分析现有精梳机锡林变速机构的原理和不足,提出了用一种双联双曲柄机构来实现精梳机锡林的变速传动。为保证锡林机构转动角速度与工艺运动要求偏差尽可能小,利用MATLAB优化工具箱求解各杆件的几何参数;利用优化结果在ADAMS中建立仿真模型并进行运动学仿真,得到了较理想的设计结果。

Through the analysis of the principle and disadvantage of the speed change mechanism used in the comber cylinder,a double-linkage double crank mechanism which can realize variable speed rotation is presented.In order to minimize the deviation of angular velocity between actual cylinder mechangsm rotation and technological requirements,geometric parameter of the double-linkage double crank mechanism is solved by using MATLAB optimization toolbox.According to the optimization results,the kinematics simulation model of the double-linkage double crank mechanism is built in ADAMS,the design is checked by the kinematics simulation in which a good result is obtained.
