摘要
为提高平台稳定性,提出一种基于单柱式(Spar)平台的新型多浮体平台,采用Fortran编程通过AQWA预留接口实现与AeroDyn的集成,基于辐射/绕射理论并结合有限元方法,对比分析风波耦合作用下新平台与Spar平台的动态响应特性。结果表明:新平台幅值响应算子除纵荡方向稍大于原平台外,垂荡和纵摇方向均显著减小;两平台所受一阶波浪激振力/力矩随频率变化趋势大致相同,且新平台纵荡和纵摇方向一阶波浪激振力/力矩均小于原平台;时域分析中,新平台除纵荡响应大于原平台外,纵摇和艏摇响应均比原平台小,其中,纵摇响应减小幅度最大,艏摇响应次之;功率谱分析中,新平台三个自由度的响应谱峰值均小于原平台。
In order to improve the stability performance,a new multi-floating platform based on the Spar platform was proposed.Fortran programming was used to realize the integration with the AeroDyn through the AQWA reserved interface.Based on the radiation/diffraction theory and by virtue of the finite element method,the dynamic response characteristics of the new platform and the Spar platform under the coupling effects of wind and wave were compared and analyzed.The results show that:the heave and pitch response amplitude operators of the new platform decrease significantly,but the surge response amplitude operator is slightly larger than that of the Spar.The first-order wave excitation force/torque on the two platforms vary with the frequency with a roughly same tendency.The first-order wave excitation force/torque in the surge and pitch directions of the new platform are smaller than those of the Spar.In the time domain analysis,the pitch and yaw responses of the new platform are smaller than those of the Spar,but the surge response is larger than that of the Spar,in which the pitch response decreases the most,followed by the yaw response.In the power spectrum density analysis,the response spectrum peak values of the new platform in surge,pitch and yaw are all smaller than those of the Spar.
