摘要：

随着造船、石油化工、锅炉、压力容器等行业的发展，超大型数控船用卷板机已成为目前卷板机的重要发展方向之一。分析了卷板机现有设计方法的弊端，建立了上辊的力学模型，根据三辊卷板机的工作原理，对上辊进行受力分析与计算。通过假设一系列支反力的大小，模拟上辊在受到均布载荷及假设的6个集中力的双重作用下，找到接近最大允许挠度的辊子挠度值，从而逆推近似求得6个支撑点的集中力。最后，把逆推出来的集中力作用到上横梁，采用ANSYS软件模拟，确保上横梁挠度小于上辊挠度；调整上横梁的惯性矩，并对其做结构优化。

With the rapid development of ship building industry，petrochemical engineering, boiler and pressure vessel, the ultra-large type CNC marine roller machine has been one of the important development directions in the field of roller machine. The disadvantages of currently design methods of roller machine were analyzed，and the mechanical model of upper roller was established. Based on the working principle of three-roll roller machine， the force situation of upper roller was analyzed and calculated. The uniform load and six assumed concentrated forces impacted on upper roller were simulated by assuming the values of a series of reacting forces，and the reflection of roller which is the nearest to the maximum reflection was found，then the concentrated forces for the six supporting points were approximate calculated by inverse method. Finally, by ANSYS simulation，the obtained concentrated forces were impacted on the top beam to ensure that the reflection of top beam was smaller than that of the upper roller. Then, the inertia moment of top beam was adjusted, and the structure was optimized.
