Method for determination of dynamical friction coefficient includes compression of sample made as rectangular parallelepiped of one material with force N between flat surfaces of two samples made of another material, with affecting it through elastic element with shear load F, that is normal to force N, with registration of values N(t) and F(t), that change in time t, increase of shear load F to value F(t) at which shift of sample takes place. One measures lengthof elastic element with registration of its deformation δ(t), that changes in time t, by dependences δ(t), N(t) and F(t) one determines values that correspond to time instant t> tfor slide velocityof samples one with respect to another, force of reaction N(t) and shear load F(t) respectively. One determines dynamical friction coefficient k(c) for materials used at slide velocity c(t) by formula |
