Abstract:

In order to increase the speed of rapier loom, the change rules and the distributions of the equivalent moment of inertia on main shaft of all components of its driving system as well as the changing rules of the inertial load on the loom were studied, and the proportion rule of the motion components of the loom to the equivalent moment of inertia on main shaft was obtained. For a WL680  type rapier loom with a reed width of 360 cm, by the structure optimization optimization, the  weight of rapier and ribbon is reduced by 28.26%, and the movement of inertia of the rapier wheel is reduced by 43.73%. A prototype was designed. The simulation results showed that the equivalent moment of inertia on main shaft of the optimized loom is reduced by 27%, and as the loom width decreased, the effect of this method reduces obviously. The physical prototype test shows that the vibration and power consumption of the optimized loom reduce obviously when running at the same speed, the highest speed of the optimized loom increases by 7% -8%. The results show that although the weights from rapier and ribbon are light and the moment of inertia of the rapier wheel is small, their influences on the equivalent moment of inertial load of main shaft are sensitive, and it is great helpful to increase the loom speed and to reduce the vibration and power consumption of the loom by reducing its weight and moment of inertia.

Key words: rapier loom, equivalent moment of inertia on main shaft, inertial load, vibration, power consumption
