Abstract
The factors of increasing productivity, reducing the cost and the quality improvement in weaving machinery are the most important research concerns. Increasing the effectiveness and productivity 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 most parts of the weaving machine that causes vibrations and noise which are important factors that influence high-speed development of looms and decrease of its performance. In this work, the mechanical factors such as stresses and vibrations were studied for the weaving machine heald frame. The finite element analysis model was designed for the heald frame and simulated the operating system using different types of composite materials with specifications that contribute to reducing vibrations and high stresses, such as high strength and light weight, and the materials used are carbon fibers and glass fibers. Also the value of the natural frequencies, vibration mode shape and stress results were calculated from the (ABAQUS) program, where the results showed a significant improvement with the use of these different materials. Thus, it can be said that the failure of the performance of the heald frame is mainly due to vibrations and frictions between the heald frame and each other during operation.
