OPTIMIZATION OF SOME WEAVING MACHINE PARTS DESIGN.
THEORETICAL APPROACH

The factors of increasing productivity, reducing the cost and the quality improvement are the most
important research concerns in weaving machinery. Increasing the effectiveness and productivity of production
were achieved by increasing the operating time and efficiency of weaving looms. Thus, the manufacturers of
weaving equipment attempt to minimize factors that limit production speed and production conditions. Heald
frame is one of the known parts of the weaving machine that causes vibrations and noise which are important
factors that influence high-speed development of looms. In this research work, study of mechanical factors
(stresses and vibration) has been investigated for heald shaft. Finite element model of the heald frame was
constructed to simulate different type of material. Then some important natural frequencies and vibration modes
are calculated and the results. Results show a major improvement with the usage of these different material. As
well as the failure of heald shaft is mainly due to friction and vibration and not due to the stresses or weight.
