The Study Of Computer Simulation Method Based On Pin-on-Disc Wear Test

With the rapid development of modern industry, science and technology, people's demand on the reliability of machinery is more and more high, the people pay more and more attention to the tribological features. Many cases had proved that the main reason, which made machine slut down, isn't the damage of components in machinery, but the wear of components of the machine. Provided we can forecast the life of machines, we also could avoid mechanical accidents and get great benefit. When the researches study the tribology systems hi the past time, most of then: results are carried out by a mass of tests, this method can get well results in a certain extent, but it is complex, strenuosity and time waste, the results are difficult to transfer.On the basis of tribo-system theory by integrating computer software with tribology knowledge, this system contains many functions such as stress analysis in the containing area, wear volume and wear tune calculation, wear surface topography simulation and wear gain imitation. During the development of simulating system, the method, which the datum combined with the computer simulation, is adapted. Based on the research of physical modal, some affecting factors of wears results were analyzed, and then different modals in the different running period were derived.The main research results are concluded as below.(1) The simulating calculation of wear volume should be based on three different stages; the wear process and volumes will be well simulated hi this way.(2) The wear times and volumes is calculated according to the actually conditions, which is more signification than the former research which concentrates on the line-wear and weight-wear.(3) Analyzed the effect of work conditions and other factors, the different effect on different wear stages is considered.(4) Based on wear parameter and experience data, the imitated wear particle and surface images of components were given. These are very useful for the fault diagnosis and wear particle analysis.
