时空船舶AIS轨迹分析

该文对原始AIS轨迹数据进行了重建、压缩和预测。首先是数据重建,将部分原始数据的位置信息可视化,筛选异常值,之后分别利用了三次样条插值和埃尔米特型插值构建丢失数据及异常点。其次是数据压缩,主要运用Douglas-Peucker算法,结合压缩质量和压缩率,选取最优的压缩阈值。最后是数据预测,该文主要运用了时间序列分析中的指数平滑模型、ARIMA模型分别预测。     

Dynamic Simulation on Collision Between Ship and Offshore Wind Turbine简

By using ABAQUS/Explicit, the dynamic process of an offshore wind turbine（OWT） stricken by a ship of 5000DWT in the front direction is simulated. The OWT is located on a large-scale prestressing bucket foundation constructed by an integrated installation technique. According to the simulation results, under the ship collision, a cer-tain range of plastic zone appears within a local area of arc transition structure of the bucket foundation, and the con-crete plastic zone is seriously damaged. As the stress level of OWT tower is relatively low, the OWT tower is less af-fected. A great inertial force is generated at the top of the OWT tower as the mass of nacelle and blades is up to 400 t. The displacement of the tower is in the opposite direction of the ship collision at the end of 1 s under the action of iner-tial force. There is only a minor damage in the ship bow. Most of the kinetic energy is transformed into the plastic dissipation and absorbed by the arc transition structure of bucket foundation.
