The paper has succeeded in achieving coupled dynamic analysis from traditional analysis mode with single hydrodynamic effect considered to coupled analysis mode with hydrodynamic-structure system coupled effect considered. 本文成功地实现了从传统的单一水动力效应分析方式到水动力-结构体系多效应耦合分析方式的跨越。
Through the experiments, it is proved that, compared with hydrodynamic model, the surface free energy based mode is more accurate description of the ink-jet printing imaging quality, and has less hypothetical conditions. 通过实验证明,基于表面自由能的模型比基于流体力学的模型更能准确的描述喷墨印刷的网点成像的质量,且假设的条件更少。
The simulation results show that the mathematic model built in this thesis can relatively truly reflect the hydrodynamic responses of the ROV under certain sea states, the fuzzy sliding mode controller performs well in motion control, the numerical calculation method is effective for the ROV motion simulation. 仿真结果表明,建立的数学模型能较为真实地反映带缆遥控水下机器人在一定海况下的水动力响应,设计的模糊滑模控制器性能良好,提出的数值计算方法是有效的。
For the case of hydrodynamic noise, in which the range of the frequency-thickness product of interest is relatively low, the symmetric zero-order mode dominates the noise radiation. 对于水动力噪声情况,感兴趣的频率厚度乘积相当低,这时零阶对称模式对噪声辐射起主要作用。
