摘　　要：主要阐述了波纹膨胀节公称位移试验技术 ,因为波纹膨胀节的补偿能力源于波纹管的弹性变形能力 ,其中包括拉伸、压缩、横向、弯曲以及它们的组合变形。公称位移是波纹膨胀节使用设计中非常重要的功能参数 。The technolgy for testing rated deflection is described. The deflection compensation ability of bellows expansion joints comes from the ability for elastic deformation, and it includes the extending, compress, lateral, angular and the combinations. The rated deflection of bellows expansion joints is a very important function parameter in the applications and the design. It can't be ignored in applications area for system safety and life.
