GENERALIZATION OF DYNAMIC RESEARCHES TO THE DETERMINATION OF THE LOAD OF KNITTING NEEDLE

Abstract

Generalization of dynamic researches of knitting mechanism of hosiery machinery for example of knitting needles for obtaining theoretical information on the spectrum of their loads, which are used in further calculations for fatigue longevity in deterministic and probabilistic aspects.  Is used the methods for describing and analyzing complex technical systems for audit of a set of dynamic calculations in the context of interaction knitting needles with various cams.
Findings. Is considered the possibility of using dynamic models of needle interaction in the knitting system  at  the  design  stage  for  obtain  a  quantitative  picture  of  their  loading  and  determine  the  zone  of
rational design parameters of the system for a given fatigue longevity of needles. Originality.  Is  consists  in  subsequent  development  of  theory  and  methodology  for  mathematical maintenance for the design of high-speed hosiery machinery. Is applies for complex assessment and analysis
of  the  refined load  spectrum  for  determination  of  longevity  of  knitting  needles by  the  criterion  of  fatigue strength. Practical  value.  Are  presented  information  that  promotes  a  comprehensive  approach  to  the
analytical definition of the loads spectrum, which increases the quality and efficiency of project solutions for ensuring a given fatigue longevity of needles in a wide range of speed regimes of the hosiery machinery.
