The dynamic behavior research of coupling shafts in tufted carpet looms

摘要

Firstly, based on the structure of tufted carpet looms (DHGN801D-400), the lumped parameter models were built, in which included the massless shafts, lumped masses, disk and elastic support. Secondly, according to various parts of the relationship between force and deformation, the transfer matrix of right and left ends were established, thus the universal transfer matrix of shaft units was determined by solving the various parts transfer matrix simultaneously. Thirdly, the dynamic behavior model of coupling shafts in tufted carpet looms was given, and different natural frequencies were acquired by simulating the model in Matlab. Lastly, the dynamic behavior model using transfer matrix was verified to be effective and feasible by experiment.
