摘要

本研究是关于应用基于Abkowitz模型的四自由度（4DOF）操纵数学模型来评估具有初始不对称性的受损船舶操纵性。使用海军研究办公室翻滚房屋船体的缩放模型作为测试模型，该模型带有损坏的舱室。根据海军舰艇的生存能力规定，受损舱室的设计和位置靠近船头，因此它有一个初始的跟部和纵倾。对受损船舶模型进行了静态和动态捕获模型试验，以确定机动数学模型的机动系数。利用捕获模型试验数据和4DOF机动数学模型进行了机动仿真。机动中的推进速度在受损状态下比在完好状态下降低得更多，右舷转弯时机动性能严重下降。

Captive Model Tests for Assessing Maneuverability of a Damaged Surface Combatant with Initial Heel Angle

The present study is about the application of a four-degree-of-freedom (4DOF) maneuvering mathematical model based on Abkowitz’s model for assessing damaged ship maneuverability with initial asymmetry. A scaled model of the Office of Naval Research Tumblehome hull with a damaged compartment was used as the test model. Based on the survivability regulations for naval vessels, the damaged compartment was designed and located near the bow, such that it had an initial heel and trim. Static and dynamic captive model tests were performed on the damaged ship model to determine the maneuvering coefficients for the maneuvering mathematical model. Maneuvering simulations were carried out with the captive model test data and 4DOF maneuvering mathematical model. The advance speed in the maneuver reduced more in the damaged condition than in the intact condition, and maneuverability was severely degraded during starboard turning.

期刊介绍： Original and Timely technical papers addressing problems of shipyard techniques and production of merchant and naval ships appear in this quarterly publication. Since its inception, the Journal of Ship Production and Design (formerly the Journal of Ship Production) has been a forum for peer-reviewed, professionally edited papers from academic and industry sources. As such, it has influenced the worldwide development of ship production engineering as a fully qualified professional discipline. The expanded scope seeks papers in additional areas, specifically ship design, including design for production, plus other marine technology topics, such as ship operations, shipping economic, and safety. Each issue contains a well-rounded selection of technical papers relevant to marine professionals.
