本文综述了有关缸套穴蚀的观点和论述,从空化是液体的一种物性出发,提出了缸套产生穴蚀的机理,分析了内部和外部各因素之间的关系。同时,从气化动力学出发,提出了描述缸套振动以及气泡形成与溃灭过程的数学模型。最后提出了防止缸套穴蚀的途径和措施。 This paper summarizes the viewpoint and discussion about the cavitation erosion in cylinder liner. Based on a physical property that cavitation is a liquid, the mechanism of cavitation erosion in cylinder liner is put forward and the relationship between internal and external factors is analyzed. At the same time, starting from the gasification kinetics, a mathematical model describing the vibration of the cylinder liner and the bubble formation and collapse process is proposed. Finally, the ways and measures to prevent cavitation of cylinder liner are put forward.
