船舶顺浪航行的纯稳性损失研究,已成为国际航海界和国际海事组织(IMO)关注的课题之一.在Ю.И.涅查耶夫根据28艘渔船和运输船船模水池试验的船舶顺浪纯稳性损失计算方法的基础上,提出了扩展模式,扩大了其适用范围,并给出了大长宽比(船长/船宽)舰艇纯稳性损失的算例,同时实现了该扩展模式的程序化,生成了实用化的软件.最后通过与CFD试验方法和一般理论计算法所得结果的对比,验证了该扩展模式计算结果的可信度.%Research on pure loss of stability of ships sailing in following waves is becoming one of the subjects ofinter-national navigation and International Maritime Organization (IMO). Based on Ю.И. Nechaev's method[1] of the calculation of pure stability loss of ships sailing in following waves according to ship model tank test of 28 fishing ships and transport shipsan extended model is proposed, which extends the scope of application of the original algorithm, and the example of ship with large ratio of length to width is given. Also the programming of the extended model is implementedand a practical software is generated. Finally, the reliability of the extended model is verified by comparing with the results obtained from the CFD test method and the general theoretical calculation method.
