1392.全球两栖登陆艇市场报告(2016-2020年)
[铁路、船舶、航空航天和其他运输设备制造业] [2015-11-30]
Concerns over port security have been increasing in line with the rising number of seabased terrorist attacks, such as the 2008 attack in Mumbai, India, and the general rise of piracy in the Gulf of Aden. This has prompted countries to modernize the landing craft and equipment used by their respective security agencies. Amphibious landing craft have the ability to patrol coastal areas and help security agencies counter national threats, such as smuggling, drug trafficking, human trafficking, and maritime piracy and terrorism.

1398.全球轮式拖拉机市场报告(2015-2019年)
[铁路、船舶、航空航天和其他运输设备制造业,汽车制造业] [2015-10-31]
A wheeled tractor is a type of heavy equipment used to move asphalt, dirt, snow, logs, raw materials, debris, rocks, and sand during construction and mining activities. These tractors can be easily converted into loaders based on users' requirements. Various tools, such as dozer blades, buckets, and rippers, can be easily attached to the tractors to convert them into bulldozers, front loaders, and front-end loaders.

1400.尾压浪板升力研究及其对WPC耐波性的影响
[铁路、船舶、航空航天和其他运输设备制造业] [2015-10-27]
尾压浪板出现近半个世纪,较好改善了船舶性能。尾压浪板受到方尾、自由液面及鸡尾流的影响,其水动力性能极其复杂。目前大多数资料是试验探索而无理论方面的研究。采用势流理论,考虑方尾、自由液面及鸡尾流的影响,对尾压浪板升力系数斜率和零升力攻角进行研究,推导的公式和试验结果吻合良好。试验和计算表明:升力中心在船体上,升力系数斜率随Fr增加而减小,Fr>0.5左右趋于稳定;零升力攻角随Fr增加而减小,对升力系数影响较大,低速可达-19°,高速可达-6°。研究结果用于穿浪双体船(WPC)耐波性研究,尾压浪板对垂荡几乎没有影响,可减少纵摇约10%。
