摘　　要：针对绳轮开裂事故,利用有限元法,对其应力状态进行分析。研究表明,正常状态下,绳轮的应力很小,不足以使绳轮开裂;在偏载状态下,绳轮轮缘根部应力急剧增大,这是绳轮疲劳破坏的主要原因。偏载是绳轮的安装误差产生的,改善绳轮安装状况是保证其顺利运行的重要措施。Aiming at solving the problem about the rope pulley damage, the stress field of the rope pulley has been calculated by the finite element method. The results demonstrated that the stress is not large enough to damage the rope pulley under the normal condition. If the error of pulley position biased load, the stress is increased sharply on the root segment rope pulley. This will cause fatigue damage of the rope pulley. Improving the error of rope pulley position can guarantee the rope pulley operation in the normal state.
