摘要 为讨论托管架几何参数对深水管道S型铺设的影响,本文利用有限元方法,考虑了托管架结构刚度影响,分析了铺设过程中管道与托管架的接触、管道大变形等非线性问题,讨论了托管架长度、曲率半径及托辊间距和高度等参数对S-lay的影响.计算结果表明,有限元法可有效解决深水铺设的强非线性问题;托管架几何形状是提高整体铺设能力的主要参数,托辊布局影响管道局部安全,托辊高度对管道上弯段的影响更显著. 为讨论托管架几何参数对深水管道S型铺设的影响,本文利用有限元方法,考虑了托管架结构刚度影响,分析了铺设过程中管道与托管架的接触、管道大变形等非线性问题,讨论了托管架长度、曲率半径及托辊间距和高度等参数对S-lay的影响.计算结果表明,有限元法可有效解决深水铺设的强非线性问题;托管架几何形状是提高整体铺设能力的主要参数,托辊布局影响管道局部安全,托辊高度对管道上弯段的影响更显著.
