The influence of waviness of technical surfaces on the contact interaction of machine parts has been studied. The parameters of roughness and waviness of the surfaces of experimental samples according to GOST R ISO 4287-2014, the mechanical properties of the sample materials and a description of the experimental methodology are given. Theoretical dependences of the contour contact area on the nominal pressure, the parameters of roughness and waviness of the contacting surfaces and the mechanical properties of the materials of the contacting parts are proposed. It has been shown theoretically and experimentally that waviness significantly affects the size of the contact area of machine parts. It is observed that, depending on the magnitude of the nominal contact pressure, the contour area formed by elastic wave deformation ranges from a few units to several tens of per cent of the nominal contact area.
