【 摘 要 】

There are many factors affecting the resistance loss of wire rope over pulley, such as tension of wire rope, diameter of pulley, envelop angle and so on. In this paper, based on the mechanical model of wire rope over pulley, the bending effect of wire rope is considered. And the non-linear equations of exit tension with entry tension, pulley radius, envelop angle and bending stiffness are constructed. At last, the influence of various factors on resistance coefficient is analysed.
