Abstract: One of the main tasks in the development of textile machinery is to increase the rapidity of automatic looms, and consequently, their productivity. With increasing automatic loom speeds, the dynamic loads on their separate mechanisms and moving joints sharply increase. Dynamic research allows us to determine the weakest mechanisms of the automatic loom. The modern automatic loom consists of a large number of structurally different mechanisms. These are cam, lever, gear, friction and combined cyclic mechanisms. The modern automatic loom contains various mechatronic devices: A device for the automatic removal of faulty weft, electromechanical drive warp yarns, electronic controllers, servos, etc. In the paper, we consider the multibody dynamic model of the automatic loom on the software complex SimulationX. SimulationX is multidisciplinary software for modeling complex physical and technical facilities and systems. The multibody dynamic model of the automatic loom allows consideration of: The transition processes, backlash at the joints and nodes, the force of resistance and electric motor performance.
Abstract: One of the main and responsible units of Sulzer
projectile loom is picking mechanism. It is specifically designed to
accelerate projectile to speed of 25 m / s. Initial speed projectile of
Sulzer projectile loom is independent of speed loom and determined
the potential energy torsion rod. This paper investigates the dynamics
picking mechanism of Sulzer projectile loom during its discharge. A
result of calculation model, we obtain the law of motion lever of
picking mechanism during its discharge. Construction of dynamic
model the picking mechanism of Sulzer projectile loom on software
complex SimulationX can make calculations for different thickness
of torsion rods taking into account the backlashes in the connections,
the dissipative forces and resistance forces
