Numerical investigation of weaving machine heald shaft new design using composite material to improve its performance

Abstract

Abstract 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 was achieved by increasing the operating time and efficiency of weaving looms. Thus, manufacturers of weaving equipment attempt to minimize factors that limit the production speed and production conditions. The heald frame is one of the most important parts of the weaving machine that causes vibrations and noise, which are important factors that influence the high-speed development of looms and decrease their performance. In this work, mechanical factors such as stresses and vibrations were studied for the weaving machine heald frame made from composite materials. The finite element models were constructed using the ABAQUS program for the traditional heald frame made from aluminum as well as for the heald frame made from composite materials. The models were simulated using the operating system conditions of constraints and of applied loads. The composite materials used are carbon fibers and glass fibers. The mode shapes of the models as well as the generated stresses were presented. The results showed a significant improvement in use of the composite materials that can reduce the frame vibration and withstand the generated stresses.
