Abstract Wear due to over-pressure is a well-known phenomenon that appears on bush bearing under off-center load. In this context, this paper proposes a methodology to develop a new bearing inspired from a lamb elbow. This bio-inspired bearing could replace bush bearing from helicopter's system. The method starts with the analysis of the contact surfaces of the biological joint from 3D scans. That allowed to extract a revolute profile for the bio-inspired bearing. Finite element simulations were then realized to find the best clearance specification to reduce contact pressure. The bio-inspired bearing is after optimized using Design Of Experiments method.

偏心载荷下仿生轴承的游隙及设计优化

摘要 过压磨损是轴瓦轴承在偏心载荷作用下出现的一种众所周知的现象。在此背景下，本文提出了一种开发受羊肘启发的新型轴承的方法。这种仿生轴承可以取代直升机系统中的衬套轴承。该方法首先从 3D 扫描分析生物关节的接触面。这允许提取仿生轴承的旋转轮廓。然后实现有限元模拟以找到最佳间隙规格以降低接触压力。仿生轴承采用实验设计方法进行优化。
