摘　　要：利用反求测量所得的数据,使用三维造型软件Pro/E对工业高速直驱平缝机整个构件进行三维建模,并应用机械系统运动学/动力学仿真分析软件ADAMS建立虚拟样机,进行运动学仿真分析,并参数化分析了刺料与挑线机构的工作特性,实现了基于仿真机构的动平衡分析,为物理样机的试制和改进设计提供了依据。最后利用ANSYS有限元分析方法对平缝机整机进行了模态分析,指出了避免部件共振的方法。Based on the reverse measuring data of the high-speed lockstitch machine, using 3-dimensional plotting software Pro/ Engineer,this paper sets up 3-dimensional models for sewing components. It also uses ADAMS to establish virtual prototyping model and do kinematic simulation. The results provide the basis for trial-manufacture of physical prototype and betterment design. It also realizes the dynamical balancing based on the computer simulation. Finally,this thesis applies modal analysis to the rotating shafts and whole machine ,and points out the method of avoiding resonance.
