摘要

为探究内压载荷作用下船用多层U 形金属波纹管的静刚度特性，以口径 250mm 多层U 形金属波纹管为研究对象，开展内压耦合作用下的静刚度试验与数值仿真研究，分析内压载荷对波纹管静刚度性能的影响规律，并推导该型波纹管在内压载荷下的静刚度预报公式，可为内压工况下多层金属波纹管的设计提供理论参考。

Abstract

To investigate the static stiffness characteristics of marine multi-layer U-shaped metal bellows under internal pressure load, a multi-layer U-shaped metal bellows with a diameter of 250 mm was taken as the research object. Static stiffness tests and numerical simulations under coupled internal pressure were carried out to analyze the influence law of internal pressure load on the static stiffness performance of bellows. A prediction formula for static stiffness of this type of bellows under internal pressure load was derived, which can provide a theoretical reference for the design of multi-layer metal bellows under internal pressure conditions.
