建立了一种考虑多种非线性因素的张力腿平台(TLP)分析模型,其中包括六自由度有限位移,各自由度之间的耦合,瞬时湿表面,瞬时位置,自由表面效应及粘性力等因素引起的非线性.推导出TLP六自由度非线性运动方程.对某典型张力腿平台ISSC TLP进行了时域上的数值计算,求得该平台在规则波作用下的六自由度运动响应.用退化到线性范围的解与已有解进行了对比,吻合良好.数值结果表明,综合考虑非线性因素后响应明显改变,建议在设计TLP平台的时候,考虑非线性因素的影响. |

theoretical model for analyzing the nonlinear behavior of a TLP is developed,in which multifold nonlinearities are taken into account,i.e.finite displacement,coupling of the six degrees of freedom,instantaneous position,instantaneous wet surface,free surface effects and viscous drag force.Based on the theoretical model,the comprehensive nonlinear differential equations are deduced.Then the nonlinear dynamic analysis of ISSC TLP in regular waves is performed in the time domain. |
