The Asia-Pacific region continued to lead global industry growth over the last six months, with aviation and tourism accounting for more than 24 million jobs and US$500 billion in economic activity.

Earthmoving equipment refers to heavy equipment used in the construction industry to move large amounts of earth, dig foundations for buildings, and landscape areas. The various types of earthmoving equipment include construction tractors, excavators, and loaders. The earthmoving equipment market in Turkey is expected to grow at a CAGR of 5.88% during the forecast period. An increase in power and energy infrastructure construction and the government's Vision 2023 in infrastructure development are the major contributors for the steady growth of the market in Turkey.

在追越情况下,船间干扰力作用时间更长,危险程度相对更高,现有的船间水动力干扰模型较为复杂而不能在实际中应用。因此,为建立适用于航海实践的船间水动力计算模型,快速估算船间水动力干扰影响,对现有船间干扰力模型进行简化。首先固定两船横距,分别采用傅里叶、高斯以及正弦函数方法对已有试验数据进行回归拟合,通过系数优化及加入横距变化影响,得出一个仅依赖于船舶纵距与横距的船间水动力计算模型。对该模型进行验证,证明所得模型精度较高。

为解决传统系泊方式中存在的工作效率低、环境差和安全隐患大等问题,将电磁技术应用到船舶系泊系统中。通过对船舶系泊的受力状态和电控永磁吸盘原理进行分析,开发一套基于电控永磁吸盘的新型船舶系泊装置,详细介绍其基本结构和工作原理。通过实例对该装置进行验证计算,并与传统的系泊方式进行对比分析。该研究为现代船舶系泊系统的发展提供了新思路,为船舶电磁系泊设备的开发和实际应用奠定了理论基础。
