摘要

仿生虎鲸作为仿生机器鱼的一类,在海洋开发和科学考察研究中具有重要的作用。基于扑翼运动原理,以鱼类推进方式设计的仿生虎鲸,其受载具有非线性、时变性和强耦合性,通过对仿生虎鲸在水中直行和转弯运动工况的分析,建立仿生虎鲸的受力模型;基于Matlab进行了仿生虎鲸的瞬时负载数值模拟,生成了仿生虎鲸瞬时负载数值模拟的文本文件,并利用Adams样条曲线函数成功实现了将瞬时负载导入仿生虎鲸的虚拟样机刚柔耦合模型中,为定性定量的分析仿生虎鲸虚拟样机刚柔耦合可靠性提供了方法与条件。结果表明,Matlab能准确的模拟仿生虎鲸瞬时负载的周期性变化,为仿生虎鲸的可靠性研究提供了明确的量化数据。

Abstract

As a kind of bionic robot fish,bionic killer whale played an important role in ocean development and scientific investigation.Based on the theory of flapping wing movement,the biomimetic killer whale was designed in the way of fish propulsion,the load was nonlinear,time-varying and strongly coupled.The bionic killer whale‘s force model was established through the analysis of the bionic killer whale’s straight line and turning movement.The instantaneous load’s text file of bionic killer whale was generated by MATLAB,the instantaneous load was successfully introduced into the rigid-flexible coupling model by ADAMS spline function,which provided a method and condition for qualitative and quantitative analysis of bionic killer whale’rigid-flexible coupling reliability analysis.The results show that MATLAB can accurately simulate the periodic change of the bionic killer whale’s instantaneous load,providing a clear quantitative data for the bionic killer whale’s reliability research.
