摘　　要：随着造纸及整饰设备向高速、宽幅、强化过程方向发展,包括:高线压压榨辊、高冲量压榨辊、宽压区压榨辊、热压榨辊、光泽压榨缸、抗挠辊、可控挠度辊等各种特殊结构、大直径、高线压辊(缸)的设计已成为现代造纸设备发展突出的关键技术之一。为进行这类辊(缸)壳横截面变形的计算,文中采用能量方法,导出了相关的计算式,提出了简化计算方法,给出了辊(缸)壳横截面径向位移系数计算图、表和重心位移系数表,可方便地用于设计计算和校核计算。Paper-Making and finishing equipment have been developed toward high speed, broad-wide, intensified processing which including： high linear press roll, high impulse press roll, wide-pressed area press roll, heat press roll gloss press vat, anti-deflection roll, controlled deflection roll etc. The designs of all kinds of these special structures with large diameter, high linear press roll （vat） have become one outstanding key technique in the development of modern paper-making equipment. In order to calculate such kind roll （vat）＇ s cross-section deformation, the paper derived corresponding calculating formula with enegy method, put forward simplified calculating method, the radial displacement coefficient calculating diagram and table for roll （vat） cross-section and gravity centre displacement coefficient table. All these can be easily used in design and check calculation.
