许多海洋物种都表现出在海洋环境中运作的人造系统所需要的能力。然而，在不减损潜力的情况下，如果生物灵感要证明是有益的，那么在比较工程系统和生物系统的性能时，重要的是要有一套一致的指标，允许公平比较，没有偏见。在这项研究中，我们专注于推导出一个无偏的性能指标适用于海洋动物和工程水下航行器的最基本的属性之一，即运动的能量成本。我们提出了一个合理的分析模型背后的运动的总能量成本的物理适用于生物和工程自主水下海洋系统。该模型建议使用等效球体效率作为比较工程和生物系统的公平度量。然后利用该模型来确定质量、速度、球体效率和酒店负载的变化如何影响系统的性能。(C)2015作者爱思唯尔有限公司出版
Many marine species exhibit capabilities that would be desirable for manmade systems operating in the maritime environment. However, without detracting from the potential, if bioinspiration is to prove beneficial, it is important to have a consistent set of metrics that allow fair comparison, without bias, when comparing the performance of engineered and biological systems. In this study we focus on deriving an unbiased metric of performance applicable to marine animals and engineered subsea vehicles for one of the most fundamental of properties; that of the energy cost of locomotion. We present a rational analytical model of the physics behind the total energy cost of locomotion applicable to both biological and engineered autonomous underwater marine systems. This model proposes the use of an equivalent spheroid efficiency as a fair metric to compare engineered and biological systems. The model is then utilised to identify how changes in mass, speed, spheroid efficiency and hotel load impact the performance of the system. (C) 2015 The Authors. Published by Elsevier Ltd.
