原油转驳船海上作业定位能力需求分析（英文）

In response to the development of deep-sea oil and gas resources, which require a high degree of cooperation by crude oil transportation equipment, a new type of ship known as the cargo transfer vessel(CTV) has been developed. To provide a theoretical reference for the design and equipment of the CTV's dynamic positioning system, in this paper, we take the new deepwater CTV as the study object and theoretically and numerically analyze its operation, wind load, current load, wave load,and navigational resistance in a range of Brazilian sea conditions with respect to its positioning and towing modes. We confirm that our proposed method can successfully calculate the total environmental load of the CTV and that the CTV is able to operate normally under the designed sea conditions.     

弹性地基梁板的径向基函数逼近求解方法

基于Winkler模型对弹性地基梁和弹性地基板的挠度求解提出了一种新方法。利用加权余量法中的配点法结合径向基函数逼近得到挠度近似解,该方法无需划分网格且无需积分是未知数与方程数目一一对应的强形式解法。数值实验表明：该近似解结果与理论解基本吻合,计算效果与杂交边界法相当,优于滑动最小二乘法;此外,根据边界条件可赋予附加未知量物理意义,将部分特征矩阵构造成单位阵从而降低了待求方程组的求解难度,减小误差,为特征矩阵附加行的编写提供了新思路。
