基于3D打印的轻量化静压空气轴承设计与流体动力学性能优化
Design and Fluid Dynamics Analysis of Air Bearings Based on 3D Printing
摘要
Abstract
Traditional hydrostatic air bearings,which are constrained by manufacturing process limitations,have difficulty achieving complex flow channel structures.To meet the extremely lightweight requirements of aviation parts,a lightweight hydrostatic air bearing was designed through topology optimization on the basis of 3D printing technology.Additionally,Fluent computational fluid dynamics simulation software was used to analyse the bearing model,aiming to solve problems such as the heavy weight of traditional bearings and uneven air flow distribution.The results show that there is a positive linear correlation between the air supply pressure and the bearing capacity of the air film and that increasing the air supply pressure can increase the bearing capacity of the air bearing.This work provides a new method for further studying the performance and weight reduction work of aviation air bearings through relevant research.关键词
