Finite element simulation of pressing fabric switch at low speed

摘要

The partial weave of a through-interlocking fabric switch has been simplified, and the 1/3 twill woven fabric model is set up. Finite element software Workbench has been used to simulate the dynamic response of 1/3 twill woven fabric compressed at a low speed by a sphere and to analyse the compressive deformation process of the 1/3 twill woven fabric. The influence of yarn material properties, the friction coefficient among yarns at crossovers, the friction coefficient between sphere and fabric, and the compression traverse of sphere on the compressibility of through-interlocking fabric switch are studied. The results reveal that the pressing pressure of the fabric switch increases with the increase in elastic modulus of insulating yarns, the friction coefficient among the yarns at crossovers, the friction coefficient between sphere and fabric, and the height of supporting part.
