In connection with an effect on development of dynamic model of beat-up process, beat-up force and weaving condition, this study has investigated a correlation of 4 kinds of weaving factors (warp tension, weft thickness, weft density and shedding height) that affect beat-up force through an experimental method and analytic method. A simulator was developed to imitate beating, shedding, and insertion motions for weaving and the experiment was performed using the simulator. The experiments showed following results: First, the beat-up force increased proportionally as the warp tension increased. Second, the beat-up force increased with the increase of the weft thickness. Third, the beat-up force was exponentially inversely proportional to the weft density. Finally, the beat-up force was increased with the increase of the shedding height. Various experimental and simulation methods were performed to investigate the contribution of the principal weaving parameters to the beat-up force.
