Mathematical Modeling of Yarn Winding Tension

Fibre Chemistry - The problem of mathematical modeling of synthetic yarn tension in the transporting area of the take-up and winding device is investigated. Based on balance of moving masses, a...     

Study of dynamics of variable structure lever mechanisms

The problem of dynamics simulation is considered for cyclic lever mechanisms having a variable structure whose variations are caused by transition of the system from an idle run to a working one and vice versa. The study is performed using as an example the material transportation gear with lower and upper toothed racks for sewing machines used in the clothing, tanning and haberdashery, foot-wear, etc., industries.
