Modelling and Simulation of a Bio-Inspired Vibration Isolator Based on the Leg of Sparrow

Bio-inspired design, or biomimicry, is a creative approach that takes inspiration from nature to improve the quality of human life. These principles have been utilised since the earliest days of human civilisation. By studying and replicating the solutions that living organisms have developed over millions of years, we can create more efficient and sustainable innovations. In mechanical engineering, one application of bio-inspired design is the development of vibration isolators. These devices mimic the natural behaviours of organisms, such as the way a bird's feet absorb impact when landing. Bio-inspired designs offer innovative solutions for vibration isolation. A dynamic modelling and simulation study was conducted to examine the effect of parameters in bio-inspired vibration isolators that mimic the shape of a Sparrow bird leg on dynamic responses like displacement and acceleration. This simulation was performed using MATLAB software. The study aimed to assess how these parameters influence dynamic responses and evaluate the effectiveness of the Sparrow bird-leg-inspired design in isolating vibrations. The modeling and simulation results demonstrate that using the parameter variations α1=750, α4=1200, L2=L6=0.130mm, L3=L4=0,060 m achieves the best displacement reduction reaching 57.33% from the initial amplitude of 0.003 m, with a maximum displacement value of 0.00128 m.
