摘要

The article describes simulation tests of the basic element forming a spacer knitted structure in a newly-designed warp knitting machine with 4 guide needle bars. It refers to a concept of forming 3D knitted fabrics already developed. In the first part of the article, the introduction, a geometric-kinematic model of the feeding and knitting zones is described. In the next part, the main one, a dynamic model of the key area isolated, that is the arrangement: beam whip roll guide needle bar of the filling, is presented. The method of performing simulation tests of the model is described. Its susceptibility to input values in the range of values accepted was studied. The times of phases of the kinematic cycle, stiffness, damping, initial load of the model elements and their mass were changed, variations in the initial values were registered: forces in warp threads, as well as the driving force and power The significance of the research results for further stages of constructing 3D warp knitting machines, mainly for the selection of driving actuators of the machine, is highlighted.
