Research On Simulation Experiment Method Of Piston Ring And Cylinder Friction And Wearing

Along with the fast developrient of research on piston ring and cylinder friction and wearing, fast and reliable simulation experiment method and rational estimation means are cried for. Tn this paper, by means of the study on simulation experiment method of piston ring and cylinder friction and wearing, advanced tie data acquire and process system, and develop the A/D hoard and acquirement and processing software. At the same imt I n~tk~ part in the development of the real梩ime demarcate device. The new data acquirement and process system weaken the disturbance and drift due to temperature variance in process of data acquirement. The real梩ime demarcate device make us get the more accurate friQtion (ioefl i ci en t.In order to evaluate the repeat performance and reliability, we do the repentance test, the result show that the experiment and test. system is good at repentance. Then the ~xperiment ot contrast test for 4 kinds ot< piston ring was done. It is show that the TiCN multi梤ing has the best performance in friction and wearing.
