摘要

为了解决浅水域探测型无人水下航行器探测模块长时连续工作时对能源的需求

设计了基于海洋动能的晃动发电装置

根据拉格朗日方程建立了航行器与晃动摆耦合的运动方程

最后根据简化的运动方程

采用龙格库塔方法求解并分析了影响晃动发电性能的因素

研究了不同海况下航行器运动幅度、周期、摆长、质量、转动惯量等参数以及不同运动耦合对发电性能的影响。在2级海况下

最佳电机阻尼系数为5.4 N·m·s/rad

3种激励运动耦合时发电装置平均功率能够达到0.5 W。研究分析表明

提出的基于海洋动能发电装置模型是合理可行的

在一般海况下

能够满足探测模块的能源需求

同时发现运动幅度、周期、摆长、质量以及耦合横摇运动对发电性能影响较大

转动惯量以及耦合垂荡运动对其影响较小。研究结果为后期晃动发电机的研制、工程试验及优化

提供了一定的理论基础与借鉴。

Abstract

To deal with energy demand of detection module of a detection unmanned underwater vehicle(UUV)for long continuous operation in shallow water

a rocking energy generation device in terms of ocean kinetic energy is proposed. The coupled motion equations for the vehicle and the rocking pendulum are established according to Lagrange equation. The factors affecting rocking generation performance are analyzed by solving the simplified motion equation with Runge-Kutta method. The influence of parameters on the rocking generation is investigated over a range of sea state

such as vehicle movement amplitude

period

pendulum length

and mass and moment of inertia with different coupling motions. Under sea state 2

the optimum damping coefficient for maximum power output gets 5.4 N·m·s/rad

and the average power output under three coupling excited motions reaches 0.5 W. The proposed ocean kinetic energy generation device model is reasonable and feasible

which meets the energy demand of the detection module under the general sea state. It is found that the amplitude

period

length

mass and the coupling rolling motion exert obvious impact on the rocking generator

but the moment of inertia and coupling heaving motion affect slightly.
