Abstract

Inspired by the safe landing of cats falling from high altitudes, a bionic flexible rubber bushing structure is proposed and its motion characteristics are systematically studied to explore its potential application in the suppression of vibration. The convex hull structure on the bushing surface is abstracted from the cat’s claw pad, and the hyper-viscoelastic model is selected as the constitutive model of the rubber material. In addition, the design with the best vibration damping effect is finally obtained by reasonably adjusting the amount of radial compression and distribution of bionic structures. Finally, under the same conditions, the test results of the dynamic characteristics of the bushing verify the accuracy of the simulation results. Research results show that the convex hull bionic structure designed in this paper can effectively change the motion characteristics of the rubber bushing under various working conditions, which provides new inspiration or potential possibility for the design of rubber bushing in the future.

基于仿生的凸壳橡胶衬套优化设计及力学仿真

摘要受高空落猫安全着陆的启发，提出了一种仿生柔性橡胶衬套结构，并对其运动特性进行了系统研究，探讨了其在抑制振动方面的潜在应用。从猫爪垫中抽象出衬套表面的凸壳结构，并选择超粘弹性模型作为橡胶材料的本构模型。此外，通过合理调整仿生结构的径向压缩量和分布，最终获得了具有最佳减振效果的设计。最后，在相同条件下，对衬套动态特性的试验结果验证了仿真结果的准确性。研究结果表明，本文设计的凸壳仿生结构能够有效地改变橡胶衬套在各种工况下的运动特性，为今后橡胶衬套的设计提供了新的灵感或潜在的可能性。
