Design and joint simulation of new needling mechanism based on ADAMS and MATLAB

设计了一种新型针刺机构,即将普通单轴单驱动针板设计成两组偏心组件对称布置的双驱动针板,并对该新型针刺机构进行运动学分析。研究结果表明:新型针刺机构产生的惯性力大幅减小,针刺运动更加稳定,平衡效果较好,且托网板瞬间承受的针刺力减小,故承载部件的弯曲变形情况得到改善,产品质量提高。同时,基于ADAMS与MATLAB建立新型针刺机构联合仿真控制系统。仿真结果表明:新型针刺机构具有较好的动态响应性能,且运行平稳,能提高针刺设备的生产效率,降低生产成本。

A new type of needling mechanism was designed,that was,the ordinary single axis single driving needle plate was designed as double driving needle plate with two groups of eccentric components symmetrically arranged.The kinematics analysis of the new type of needling mechanism were carried out.The results showed that the inertia force produced by the new type of needling mechanism was greatly reduced,the needling movement was more stable,the balance effect was better,and the needling force on the supporting plate was reduced,so the bending deformation of the load-bearing part was improved,and the product quality was improved.At the same time,based on ADAMS and MATLAB,the joint simulation control system of new type of needling mechanism was established.The simulation results showed that,the new type of needling mechanism had good dynamic response performance and stable operation,which was conducive to improve the production efficiency of needling equipment and reduce the production cost.
