项目摘要
The relationships between structure and function in animals can effectively be addressed from the standpoints of both biology and physics. This integration forms the basis of the science of biomechanics. The mechanics of fish swimming (how a fish interacts with the water to produce propulsive forces), energetics (the associated energy) and efficiency (how much energy is wasted) are well understood for fish that swim by undulating their body. This has allowed for an understanding of perfomance in relation to form and muscle powering. For example, the endurance of migrating salmon, the high sustained swimming speed of tuna and the rapid acceleration of pike as they catch their prey. However, less is known about the mechanics and energetics of fish that have a rigid body carapace and swim by undulatory motions of their fins (e.g. trunkfish, boxfish and pufferfish). My previous studies have identified a variety of adaptations that allow these forms to move efficiently at relatively low speed through complex and cluttered environments such as coral reefs. This study focuses on a number of energetically advantageous mechanical interactions between the fish's propulsive fins and its body. Theory suggests that an undulating sheet-like fin attached to a rigid body produces more thrust than the same fin executing the same motions "on its own". The purpose of this study is to experimentally confirm this effect and assess its magnitude and energetic consequences in a variety of "non-bodied swimmers". Recently, engineers have turned to biology for solutions to practical problems (bioinspiration) and boxfish and their relatives are good models for certain autonomous underwater vehicles that may be used in environmental monitoring (e.g. detecting pollutant concentrations and sources, military applications, ocean surveying) and this work will likely contribute to the design and operation of such vehicles. In particular, undulatory fins offer high efficiency and manoeuvrability. Energy savings through positive hydrodynamic interactions between the propulsor and body being propelled may protract vehicle battery life and thereby mission duration.
从生物学和物理学的角度可以有效地解决动物结构和功能之间的关系。这种整合构成了生物力学科学的基础。鱼类游泳的机制(鱼如何与水相互作用以产生推进力)、能量学(相关的能量)和效率(浪费了多少能量)对于通过摆动身体游泳的鱼类来说是很容易理解的。这允许理解与形体和肌肉力量有关的表现。例如,迁徙的鲑鱼的耐力,金枪鱼的高持续游泳速度和梭子鱼在捕捉猎物时的快速加速。然而,对于具有刚体外壳并通过鳍的波动运动游泳的鱼类(例如干鱼,箱鱼和河豚)的力学和能量学知之甚少。我以前的研究已经确定了各种各样的适应,使这些形式能够在复杂和杂乱的环境中以相对较低的速度有效地移动,比如珊瑚礁。这项研究的重点是鱼的推进鳍和它的身体之间的一些能量上有利的机械相互作用。理论表明,附着在刚体上的波纹片状鳍比同一鳍“单独”执行相同运动产生更大的推力。本研究的目的是通过实验证实这种效应,并评估其在各种“非身体游泳者”中的强度和能量后果。最近,工程师们转向生物学来解决实际问题(生物灵感),箱鲀及其亲属是某些自主水下航行器的良好模型,可用于环境监测(例如检测污染物浓度和来源,军事应用,海洋测量),这项工作可能有助于此类航行器的设计和操作。特别是,波动鳍提供高效率和机动性。通过推进器和被推进体之间的积极流体动力相互作用节省的能量可以延长车辆电池寿命,从而延长任务持续时间。
