The paper deals with the dependence of the characteristics of the Relay waves caused by impact on the properties of the surfaces of the colliding bodies. The main characteristics of the impact process - the duration of the impact, local compression, voltage in the contact area - are considered as functions of the parameters characterizing the frequency, amplitude, wavelength of the Relay and the speed of their attenuation. In the previous works of the authors the case of collision of bodies with non-deformed surfaces of high curvature has been investigated. In the given work the case of collision of bodies with small curvature of their undeformed surfaces is considered.   Comparison of the results obtained by the authors in this paper with those obtained earlier allowed us to conclude that the spectrum of Relay waves frequency does not depend on the properties of the colliding surfaces of the bodies. Obviously, the curvature of the body surfaces has a significant effect on the amplitude of the waves and the velocity of their attenuation with depth. В работе рассматривается зависимость характеристик волн Релея, вызванных ударом, от свойств поверхностей соударяющихся тел.Основные характеристики процесса удара, - продолжительность удара, местное сжатие, напряжения в области контакта, - рассматриваются как функции параметров, характеризующих частоты, амплитуды, длины волн Релея и быстроту их затухания. В предыдущих работах авторов был исследован случай соударения тел, недеформированные поверхности которых обладают большой кривизной. В данной работе рассмотрен случай соударения тел с малой кривизной их недеформированных поверхностей.Сравнение результатов, полученных авторами в данной работе, с результатами, полученными ранее, позволило сделать вывод: спектр частот волн Релея не зависит от свойств поверхностей соударяющихся тел. Очевидно, существенно влияет кривизна поверхностей тел на амплитуды волн и быстроту их затухания с глубиной. The paper deals with the dependence of the characteristics of the Relay waves caused by impact on the properties of the surfaces of the colliding bodies.   The main characteristics of the impact process - the duration of the impact, local compression, voltage in the contact area - are considered as functions of the parameters characterizing the frequency, amplitude, wavelength of the Relay and the speed of their attenuation.  In the previous works of the authors the case of collision of bodies with non-deformed surfaces of high curvature has been investigated.
