摘　　要：某宽厚板轧机主传动系统的万向节发生多次断裂事故。本文对万向节失效进行分析、主传动系统动力学仿真、万向节有限元模拟以及疲劳强度计算,计算结果表明:疲劳强度安全系数偏低,仅为1.03,是万向节疲劳失效的主要原因。In consideration that the universal joint of main driving system for certain width thick plate mill often breaks, therefore, in this paper, calculation has been made for universal joint failure analysis, main driving system＇s mechanical simulation, universal joint＇s finite element modeling and failure strength. Calculated resuits indicate that the main cause for fatigue failure of a universal joint is because of lower safety factor of fatigue strength, which is only 1.03.
