摘要
建立了喷水推进系统和船体转弯操纵的稳、动态数学模型,并考虑喷泵汽蚀的影响,对喷水推进船转弯过程中的喷泵工作状况进行了研究,为喷水推进船确定合理的转弯操纵方法提供了依据.研究内容包括不同初始航速下所有喷泵大舵角转弯、高初始航速下部分喷泵转弯和高初始航速下所有喷泵小舵角转弯这几种转弯方式下喷泵的工作状况.对计算结果进行分析后认为在非紧急情况下高航速时用部分泵实现转弯是最合适的转弯方式.
In order to constitute reasonable maneuvering rules of turning for waterjet-drived ship,a steady/ dynamic mathematical model of waterjet propulsion system is set up. The characteristics of waterjets during turning course is investigated by computer simulation based on above mathematical model ,taking account of the cavitation of waterjet. Following simulation researches are included in this paper： Operation conditions of waterjet during turning by all steering units at large steering angle in different initial ship speeds; Operation conditions of waterjet during turning by some steering units in high initial ship speeds;Operation conditions of waterjet during turning by all steering units at small steering angle. According to the analysis of simulation results it is believed that if the situation is not very emergent the manoeuvring mode of turning in high initial ship speed by some waterjets is most appropriate one.
