Влияние податливости шероховатого слоя на распределение контактных давлений в сопряжении сложнопрофильных тел

Abstract

The paper contains the results of a numerical investigation of contact pressure between the complex bodies that is setting by surfaces of complex shape and don't have simple analytical description. Influence of Winkler's layer compliance simulating the contact surface roughness is taken into account. Influence of this layer compliance and the gap distribution between the bodies on the distribution of the contact pressures were determined. The method of boundary integral equations is used for determine the contact pressure. Ratio of the boundary element method is used for sampling. In the numerical experiments the influence of the gap distribution between the contact bodies at the contact pressure distribution was investigated. Also the compliance of the elastic layer, simulating the stiffness properties of roughness surface of the contact bodies is varied. The characteristic of distribution of contact pressure and maximum contact pressure dependence of variable parameters were obtained.
