摘　　要：复合材料管已成为管道发展的热点和趋势。文中对钢带软管在同时受到内压和弯曲组合载荷作用下的力学性能进行了研究。基于建立的钢带软管的环向和径向力学平衡方程,提出了不同弯曲半径下该种类型管道的爆破压力理论计算方法。文中还进行了有限元数值模拟,并与理论计算结果对比分析,分析结果表明文中提出的爆破压力计算方法可作为此类管在同时受到内压及弯曲组合载荷作用下的通用算法,为解决此类工程问题提供重要参考。Flexible pipes have become more and more widely used as subsea pipelines. In this paper, the mechanical properties of steel strip flexible pipes under internal pressure and bending simultaneously are studied. Based on the established hoop and radial mechanical equilibrium equations, the burst pressure calculation method of this kind of pipe under different bending radius is pro posed. Finite element numerical simulations are carried out and the calculated results are compared with the theoretical prediction. Analysis results show that the burst pressure calculation method proposed in this paper can be used as general algorithm of steel strip flexible pipes under combined internal pressure and bending. The burst pressure calculation method provides an important tool to solve such engineering problems.
