基于ANSYS/LS-DYNA电脑袜机双挑双揿针器的有限元仿真分析

Analysis on Finite Element Simulation of Computer Hosiery Machine’s Double Up-and Down-Picker System Based on ANSYS/LS-DYNA

针对国产双挑双揿针电脑袜机设计手段单一,缺乏相应的理论分析基础,着重对双挑双揿针机构进行弹性动力学分析。基于SolidWorks创建了双挑双揿针器的实体模型,将该模型导入到ANSYS/LS-DYNA分析系统,对挑揿针运动过程中挑、揿针头与织针间的接触碰撞进行仿真分析,求解出在挑、揿针过程中织针的运动及受力变化情况,为双挑双揿针机构的优化设计提供了理论分析基础。

In view of the single means of design and lack of corresponding theoretical analysis foundation of domestic double up-and down-picker computer hosiery machine,elastodynamic analysis was carried out mainly on the double up-and down-picker.A solid model of double up-and down-picker was built based on the technique of SolidWorks.On this basis,the solid model was guided to ANSYS/LSDYNA analysis system,which was used for simulation analysis on the contact-collision between the knitting needle and up-and down-picker need,and also used to obtain the needle movement and changes with stress during the pick-up and press-needle process so as to provide theoretical analysis foundation for the optimal design of double up-and down-picker.
