摘要

蜘蛛网是一种复杂的结构,需要发挥多种作用,例如捕捉猎物和传递网载信号。在织网时,体重较大的蜘蛛倾向于增加网的预张力,这似乎与直觉相反,因为网越紧就会减少拦截和留住猎物的机会。在本文中,我们认为体重较大的织网蜘蛛会增加网的张力,以减少来自网底部的振动信号的衰减。我们首先建立了一个详细的蜘蛛网模型,并通过张力调整算法对其进行调整,使其符合实验观察到的曲线,从而支持我们的观点。然后,我们使用最先进的有限元分析工具研究了蜘蛛重量和蜘蛛网张力对信号传输特性的影响。

Effect of spider's weight on signal transmittance in vertical orb webs.

Spider orb web is a sophisticated structure that needs to fulfil multiple roles, such as trapping prey and transmitting web-borne signals. When building their web, heavier spiders tend to increase the pretension on the web, which seems counterintuitive since a tighter web would decrease the chances of stopping and retaining prey. In this article, we claim that heavier orb-weaving spiders increase tension on the web in order to reduce the attenuation of the vibratory signal coming from the bottom part of the web. We support our claim by first building a detailed spider web model, which is tuned by a tension-adjusting algorithm to fit the experimentally observed profiles. Then, the effects of the spider weight and the web tension on the signal transmittance properties are investigated using state-of-the-art finite element analysis tools.
