Finite element modeling and analysis of the presser foot of the GD2308 high speed tacking industrial sewing machine

LIU Yin1,CHU Jia-peng1,YU Ming2 1.School of Mechanical Engineering and Automation,Dalian Polytechnic University,Dalian 116034,China;2.Dalian Dafuji Sewing Machine Company Limited,Dalian 116034,China  
For vibration and noise reduction of industrial sewing machines,the finite element(FM) model of the presser foot of the GD2308 high speed tacking industrial sewing machine is established based on its structure characteristic and working performance by CATIA.The model is meshed using ANSYS for finite element analysis,and the dynamic characteristic of presser foot is analyzed.The first ten natural frequencies and the first six vibration modes of the presser foot are given.The output of computation shows that the vibration modes of the presser foot are mainly bending,twisting,and their combination.The dynamic analysis of the presser foot may predict the faults in structural design,and provide some scientific basis for reducing the structural vibration and the noise of the high speed tacking industrial sewing machine.
