摘要
以水下机器人的动态行为仿真为背景,针对单一环境下仿真水下机器人动态行为和流体动力学问题存在的局限性,提出了基于MATLAB/Simulink与FLUENT协同仿真的解决方案。首先介绍了MATLAB/Simulink与FLUENT的运行机制,分析了两个仿真环境实现协同仿真的技术可行性并提出了三种可行的接口方式。以此为基础,重点研究了FLUENT中嵌入MATLAB/Simulink与MATLAB/Simulink中嵌入FLUENT两种嵌入式协同仿真方式以及并行协同仿真方式的基本思想和具体实现方法。此协同仿真方法不仅对于研究流体环境中物体运动与流体动力紧密耦合的问题提供了有效手段,也为研究其它与流体紧密耦合的物理现象提供了解决思路。
Aiming at the dynamic behaviors simulation of underwater vehicle, a collaborative simulation scheme was proposed based on MATLAB/Simulink and FLUENT to overcome the limitation due to using single simulation platform to simulating the dynamic behaviors and hydrodynamics of underwater vehicle. The technical feasibilities were analyzed utilizing MATLAB/Simulink and FLUENT to realize collaborative simulation and three interface modes were proposed through introducing the operational mechanism of the two simulation environments. Based on the above interface modes, the fundamental principles and their implementation approaches of embedded collaborative simulation, including two modes of MATLAB/Simulink embedded in FLUENT and FLUENT embedded in MATLAB/Simulink, as well as parallel collaborative simulation were mainly studied. The collaborative simulation scheme discussed not only supplies an effective method to solve the close coupling problem between movement of object in fluid and hydrodynamics, but also offers a reference clew to research on the other physical phenomena coupling with fluid.
