Asymmetric and nonlinear unsteady loads on high speed ferries

大型高速双体船正在将其应用领域从沿海客运航线扩大到海洋货运和军事服务。这正在将可操作性标准从运动和乘客不适转变为在严重海浪环境中的结构载荷限制。本课题研究的是大浪结构荷载预测。大浪导致强烈的非线性响应，使许多分析方法失效。用许多预测方法也无法预测横向结构上的荷载。本项目将开发并通过实验完全验证预测大浪引起的非对称结构荷载的时域计算方法。

Large high speed catamarans are expanding their domain of application from coastal passenger routes to ocean freight and military service. This is shifting operability criteria from motions and passenger discomfort to structural load limitations in severe wave environments. This project investigates large wave structural load prediction. Large waves lead to strongly non-linear responses, invalidating many methods of analysis. Prediction of loads on the transverse structure is also not possible with many prediction methods. This project will develop and validate by experiment fully time domain computational methods for the prediction of asymmetric structural loads due to large waves
