Abstract

Inspired by the stabilization of a bird's head by the arc-shaped supporting structure of its neck, a nonlinear vibration isolator that imitates these properties is proposed. The geometry and stiffness properties of the isolator, which consists of three rods connected by torsional springs, are designed for a specific payload to realize an isolator with a very low natural frequency offering good vibration isolation properties over a wide frequency range. A prototype is constructed to isolate a smart phone camera mounted on a bicycle from vibration excitation due to a rough road. The results show that the isolator is effective above a frequency of approximately 1 Hz.

一种非线性隔振器，灵感来自于鸟脖子的弧形多椎体结构。

受鸟类颈部弧形支撑结构稳定头部的启发，提出了一种模仿这些特性的非线性隔振器。该隔振器由三根扭簧连接的杆组成，其几何形状和刚度特性是为特定负载而设计的，以实现具有极低固有频率的隔振器，在很宽的频率范围内提供良好的隔振性能。为了使安装在自行车上的智能手机相机不受崎岖路面引起的振动激励，构建了一个原型。结果表明，该隔离器在约1hz频率以上有效。

期刊介绍： Bioinspiration & Biomimetics publishes research involving the study and distillation of principles and functions found in biological systems that have been developed through evolution, and application of this knowledge to produce novel and exciting basic technologies and new approaches to solving scientific problems. It provides a forum for interdisciplinary research which acts as a pipeline, facilitating the two-way flow of ideas and understanding between the extensive bodies of knowledge of the different disciplines. It has two principal aims: to draw on biology to enrich engineering and to draw from engineering to enrich biology. The journal aims to include input from across all intersecting areas of both fields. In biology, this would include work in all fields from physiology to ecology, with either zoological or botanical focus. In engineering, this would include both design and practical application of biomimetic or bioinspired devices and systems. Typical areas of interest include: Systems, designs and structure Communication and navigation Cooperative behaviour Self-organizing biological systems Self-healing and self-assembly Aerial locomotion and aerospace applications of biomimetics Biomorphic surface and subsurface systems Marine dynamics: swimming and underwater dynamics Applications of novel materials Biomechanics; including movement, locomotion, fluidics Cellular behaviour Sensors and senses Biomimetic or bioinformed approaches to geological exploration.
