自动落纱机结构设计及仿真优化研究

Structrue Design and Simulation Optimization Research on Automatic Doffers

为解决传统落纱机在拔纱过程中容易对纱管和锭子造成破坏的问题,本文设计了一种新型自动落纱机。该设计利用SolidWorks软件建立自动落纱机三维模型,确立各零件的基本尺寸,然后利用ANSYS对落纱机拔管机构轨迹进行优化,得到拔管机构最优参数。同时,基于虚拟样机技术在ADAMS中对自动落纱机进行动力学仿真,获得了主动气缸动力学参数,为选择主动气缸提供了数据依据。仿真结果表明,拔管过程中纱管与锭子最小间隙为0.5mm,有效解决了传统电动落纱机在拔纱过程中存在的问题,而且极大的提高了落纱效率。该研究为自动落纱机的发展提供了更优越的方案,具有较好的应用价值。

In order to solve the problem that the traditional doffer does harm to bobbins and spindles during the process of pulling the bobbin, a new type of automatic doffer is designed. First, a three-dimension model of the automatic doffer is built in SolidWorks software. Then, themechanism of pulling bobbins is optimized in AN- SYS, and the optimal parameters are gotten. Finally, based on ADAMS software, the kinematics and dynamics analysis are completed and main parameters of the main cylinder are shown. The simulation results show that the minimum clearance between the bobbins and the spindles is 0 .5 mm , and th is design solves the problem of the traditional doffer during the process of pulling the bobbin. This design provides an excellent scheme for the development of the automatic doffer, and it has great value in application.
