    • Deformable spacers and spacer assemblies absorb energy when flange bolts are subjected to compressive axial loads by plastically deforming, failing in shear, rupturing or in a combination of failure modes so the flange bolts and the flanges connected thereby are not damaged. One deformable spacer may have a hollow cylindrical body with a plurality of elongated slots there through. Another deformable spacer may have an annular stiffener extending inwardly from an inner surface of a hollow cylindrical body. A spacer assembly may include an inner cylindrical body, and outer cylindrical body, and an annular shoulder extending from one of the bodies and engaged by the other body shears when a shear failure load is applied to the flange bolt. Another spacer assembly may include an annular belt around a cylindrical body so that the belt will rupture before the cylindrical body plastically deforms. (Fig. 3)
    • 当法兰螺栓受到塑性变形,剪切破坏,破裂或破坏模式失效时,法兰螺栓承受轴向压缩负荷时,变形垫片和垫片组件会吸收能量,因此法兰螺栓和由此连接的法兰不会损坏。 一个可变形的间隔件可以具有中空的圆柱形主体,其中具有多个细长的狭槽。 另一种可变形间隔件可具有从中空圆柱形本体的内表面向内延伸的环形加强件。 间隔件组件可以包括内圆柱体和外圆柱体以及从其中一个主体延伸并且当剪切破坏载荷施加到凸缘螺栓时由其他主体剪切件接合的环形肩部。 另一个间隔件组件可以包括围绕圆柱形本体的环形带,使得带在圆柱形本体塑性变形之前将破裂。 (图3)
