摘　　要：以流体力学为基础分析空化形成、发展的条件以及空泡溃灭的部位 ,从理论上计算空泡溃灭时所产生冲击力的大小。解释了轴瓦表面因空化造成失效的机理。得出选用表面较硬的材料、提高润滑油质量、减少油中杂质及水和空气对轴承抗空蚀有利。附图 3幅 ,参考文献 3篇。On the base of fluid mechanics,the condition of air cavitation formation and development and position of air cavitation break have been analyzed. The magnitude of impact force produced by air cavitation break up has been calculated. The failure mechanism produced air cativation on shaft bush surface is explained. It is profitable for increasing air corrosion resitance by using material with higher surface hardness, high quality lubricating oil and reducing impurity, water and air in oil.
