摘要

本文采用激光粉末床熔合(LPBF)技术制备了一种轻型增材制造(AM)固定几何流体动力推力轴承,并与传统制造的类似设计的铸铝合金推力轴承进行了实验比较。本研究的目的是评估AM轴承的减重设计特征如何影响主动临界流体动力性能参数,以更好地了解在役可行性。在各种静态工况下,测量了动水压力分布、最小油膜厚度(MOFT)、轴承温度和油温升高等性能参数。与传统制造的轴承相比,增材制造轴承的最小油膜厚度平均增加53%,尾缘动水压力平均增加116%,轴承温度平均降低1%。实验结果与数值模拟结果吻合较好。

Experimental performance evaluation of a lightweight additively manufactured hydrodynamic thrust bearing
In this paper, a lightweight additively manufactured (AM) fixed geometry hydrodynamic thrust bearing fabricated via laser powder bed fusion (LPBF) is experimentally compared to a traditionally manufactured cast aluminum alloy thrust bearing of similar design. The purpose of this study is to evaluate how weight-saving design features in the AM bearing affect active critical hydrodynamic performance parameters to better understand in-service viability. Under various static operating conditions, performance parameters such as hydrodynamic pressure distribution, minimum oil film thickness (MOFT), bearing temperature and increase in oil temperature are measured. Compared to the traditionally manufactured bearing, the AM bearing showed an average increase in minimum oil film thickness of 53 %, an average increase in trailing edge hydrodynamic pressure of 116 %, while exhibiting an average decrease in bearing temperature of 1 %. Experimental results are compared to numerical simulation showing reasonably good agreement.
