摘　　要：弹性体为深水立管柔性接头关键部件,与主体结构粘结的界面端附近为易发生损伤部位,针对其破坏机理问题,采用有限元软件ABAQUS对橡胶-钢粘结界面端的应力场及其影响因素进行分析,结果表明:橡胶-钢粘结界面端附近应力场存在明显的应力集中现象,并在θ=60°这一路径上的应力最大;改变界面端结合角可以影响橡胶-钢粘结界面端应力大小,但影响很小。Elastomer is the key component of the flex-joint of deep-water riser, which is bonded with major structure. The bonded interface corner of these two components is liable to be damaged. In order to investigate the failure mechanism, finite ele- ment software ABAQUS was used to analysis stress field of rubber-steel bonded interface comer and its influencing factor. The results showed that stress field of rubber-steel bonded interface corner would form stress concentration and the maximum stress is at the path of. The change of interface bounded angle would affect the stress magnitude of rubber-steel bonded interface comer, but this effect is small.
