摘　　要：考虑风、浪的联合作用,建立了近海风力机组的系统载荷模型。根据基于流函数理论非线性规则波的仿真方法以及Morison方程,采用C++与Fortran语言混合编程开发了极限波浪力的仿真计算程序。应用该程序对一非线性规则波进行了仿真计算,其计算结果与国外文献的波浪仿真计算结果进行比较,取得了良好的一致性,从而验证了极限波浪力的仿真计算模型;最后应用开发的程序对在波浪作用下的塔架实例的极限波浪力进行了计算。Considering the joint effects from wind and wave, a simple load model of offshore wind turbine system was built. According to the simulation method of nonlinear regular wave based on the stream function theory and Morison equation, the program used in the extreme wave loads simulation and calculation was coded using C ＋ ＋/Fortran mixedprogram. A nonlinear wave simulation was obtained using this program and the simulation results are good in agreement with those obtained by the foreign program used in the calculation of the wave loads on the offshore wind turbine. This validates the simulation and calculation model of the extreme wave loads. At last, the extreme wave loads from the wave mentioned above on a tower were calculated using the developed program. An available method of calculating extreme wave loads on the offshore wind turbine was provided by this paper.
