AHTS Shaft Alignment Database

The files here uploaded were created from the random variation of the bearings offstets of an AHTS ship and its influence coefficients matrix. They include 3 different databases (namely: the first one with 800 samples; another with 1600 samples; and the las rith 1678 sampes), and 3 different conditions (namely: ship at drydock, cold ship, and hot ship). This database were used feeding Machine Learning models in order to try to classificate if a determined set of offsets would align or not the studied shaft line system.

本次上传的文件均基于某锚作拖带供应船（AHTS，Anchor Handling Tug Supply Vessel）的轴承偏移随机变化量及其影响系数矩阵生成。该数据集包含3个样本库：其一包含800个样本，其二包含1600个样本，其三包含1678个样本；同时涵盖3种工况：船舶处于干船坞工况、冷态船舶工况与热态船舶工况。本数据集被用于训练机器学习模型，以对给定的一组偏移量集合是否与所研究的轴系系统对中进行分类判别。
