| Abstract: | In the paper,the surface contact stress during the impact process between silt particles and blade of hydraulic turbine is analysed.The influence of material property on contact stress is discussed.The results show that the surface material will yield when the particles have an impact speed of 0.65m/s.To compare with steel material,the elastic rubber coating may reduce contact stress about two orders of magnitude.At the same time,a composition structure by using buffer coating is presented. |
