  • Investigation of optimal shape/structural design of fishing lures

抄録

<p>In this study, we introduce the idea, the present research state, and the prospects for the optimal shape/structure design of fishing lures based on CAE. Since a fishing lure appeals its underwater motion or behavior, e.g., fluid-induced vibration, rotation. sound, flashing light, as baits to catch fish, we mainly investigate the vibration behavior of fishing lures and perform their shape/structure optimization for lure design. Up to now, only considering water pressure as external force on vibration lures, we have developed a gradient-based shape optimization method for enhancing their vibration behavior. Recently, considering the real analytical condition, we reproduced flow-induced vibration of fishing lures by weakly coupled fluid-structural interaction analysis and optimized their optimal structures using the Box-Behnken design. In the future, we aim to develop a gradient-based shape/structure optimization method for lure design that can make lure fishing more efficient and more interesting.</p>
