摘要

仿生虎鲸作为仿生机器鱼的一种,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,对仿生虎鲸的运动机理进行分析,利用Matlab对其瞬时负载进行了数值模拟。基于应力-强度干涉理论,建立了仿生虎鲸直行和转弯运动负载可靠性分析的状态函数,计算得到了仿生虎鲸直行和转弯运动负载的可靠性指标和可靠度,结合可靠性灵敏度分析理论,得到了仿生虎鲸运动负载的设计参数的无量纲化灵敏度,分析了设计参数对可靠性的影响程度。为在以扑翼理论为推进器的仿生水下机器人设计研究和优化设计领域提供了理论基础、准确的数据支撑和一种有效的数值计算方法,具有重要的实际工程意义。

Abstract

As a kind of bionic robot fish,bionic killer whale played an important role in ocean development and scientific investigation. Based on the flapping wing movement theory,the bionic killer whale’s mechanism was analyzed,its instantaneous load was simulated by MATLAB. Based on the stress-strength interference theory,the bionic killer’s load reliability state function was established,the reliability index and reliability of bionic killer whale was calculated,combined with the reliability sensitivity analysis theory,the dimensionless sensitivity was obtained,analyzed the influence of the bionic killer whale’s design variables to reliability sensitivity gradient. This paper provides the theoretical basis,accurate data support and an effective numerical calculation method for the design and optimization of the bionic underwater robot with flapping wing theory as the propeller,which has important practical engineering significance.
