| 摘 要： | 应用边界元方法,对双频入射波在和频及差频下的二阶速度势做了完整的求解,通过物面积分计算了任意三维结构上的二阶波浪力的传递函数.对简单几何物体,与发表的结果做了对比,两者吻合良好,验证了本方法的正确性.应用这一方法还对复杂的张力腿平台模型做了实际计算,发现在低频和高频区二阶波浪力平方响应函数有着显著的能量分布.

| Abstract: | Based on a higher-order boundary element method, a numerical model is established for complex solution of second order diffraction and radiation potentials at the sum and different frequencies in bichromatic incident waves. The second-order quadrantic transform functions are obtained by the integration of second--order fluid pressure on the they surface. Comparison ontheies with simple geometry shows that the present results are in gabs agreement with published ones. Computation on a TI-P model shows that the second--order quadrantic transform functions have distinct distribution at lower and higher frequency ranges. |
