铠装层

非粘结柔性管道的结构主要由金属层和聚合物层组成。金属层包括骨架层、抗压铠装层及抗拉铠装层。聚合物层包括内护套层、外护套层以及金属层之间的防磨层等。

Unbonded flexible pipe is a composite structure built up of several steel layers ( carcass layer , pressure armor layer and tension armor layers ) and polymer layers ( inner sheath layer , anti-wear layer and outer sheath layer ) .

第一种方法，其重点在于模拟聚合物层和螺旋抗拉铠装层，模型中没有包括骨架层和抗压铠装层，此模型仅能分析在单一的拉伸或扭转载荷作用下的结构响应。

One model is presented with its emphasis on modeling the polymer layer and helical tension armor layer . The carcass and pressure armor layers are not including , so the model can be only used to analysis the response under simplex loading .

第二种方法，采用了壳单元模拟聚合物层和梁单元来模拟抗拉铠装层钢带。

The other model used shell element to simulate polymer layer and beam element to simulate helical tendon .

结构特点本产品具有安装使用方便，能直接用电缆的铠装层提供可靠的接地，适用范围广泛，可靠性高的特点。

Structure and features it has features of convenient installation , wide application scope and high reliability , providing reliable earthing with cable armored layer .

但是铠装层有感应电流流过时，每根钢丝中磁力线形成闭合回路，涡流损耗增加。

However , while induced current flow through armoured layer , closed magnetic force line loop is shaped in each steel wire , eddy loss of armoured layer increases .

注：单芯铠装电缆仅用于直流系统，若用于交流系统，应采用非磁性材料的铠装层。

Note : A Single-core armoured cable is only applied to DC transmission system . If it is required to use in AC transmission system , non-magnetic materials shall be applied to armoured layer .
