The research of the traditional method in impact abrasive wearing often commences from experiments or real object examinations, then deduces an empirical formula or viewpoints, so gets the conclusion which is basic to belong to qualitative and after wearing investigation. In this dissertation,the author presents a systematic wearing test to imitate work circumstances of impact abrasive frication wear, which includes the different grain sizes and quantity, on the other hand,uses analysis software ANSYS to establish models in accordance with wearing test, and imitates the whole process of impact. On the basis of the calculation of ANSYS, the author gets mechanical data of different abrasive grains and amounts impact wearing surface, and join together the physics characteristic of wearing terrain, then make a direct analysis of deterioration and wearing character. This is not only very important for improves material wear life and develops tribology theory,but also transform wearing investigation from qualitative to quantitative analysis.The main work has below several aspects:(1) Establishing a set of impact abrasive wearing test system, which is used to observe the specific wearability due to the varieties sizes of grain and amounts, and put forward some viewpoints.(2) The analysis software ANSYS in usage establishes a set of analysis model to research various mechanics parameters changing that get in touch with sizes and amounts, then on this foundation to study impact abrasive wearing.
