| 摘 要： | 针对喷水推进滑行艇的高速滑行原理,建立了其非线性的纵向运动数学模型。首先分析了滑行艇在高速滑行过程中的受力,详细地推导了艇体受到的重力、浮力和动升力,并根据喷水推进器的工作原理,推导了喷水推进力的表达式;然后建立了喷水推进滑行艇的非线性纵向运动数学模型;最后设计了基于该模型的滑行艇纵向运动预报软件,并进行了高速滑行的操纵性仿真试验,仿真结果与船模试验数据吻合较好,表明了该模型能够较准确的预报喷水推进滑行艇在静水中的纵向运动。

| Abstract: | According to the high-speed sliding theory of waterjet propelled planing craft,the mathematical model for the non-linear longitudinal motion is established.Firstly,the forces on planing craft hull in high-speed sliding are analyzed,the gravitation,buoyancy,and hydrodynamic lift are presented in detail,and the expression of the waterjet thruster is deduced according to the principle of water-jet propeller.Then,the mathematical model for the non-linear longitudinal motion of the waterjet propelled planing cra... |
