Dynamic impact of super resonance screens on a direction parallel to the steel, screw-and-cylinder spring was described in details. The amounts of impact can be determined by the commonly used formulae. Lack of simple functions, describing a horizontal impact of the screen, results from not explicit description of transverse rigidity of the springs. A survey of methods used to describe the elasticity factor of cylinder steel springs on a direction perpendicular to their axes was presented in the paper. The simplest empiric formula describing the transverse rigidity basing on the spring longitudinal rigidity had been selected from the suggested methods. That formula was used for calculations of elasticity value on the direction perpendicular to spring axes in ten or so screens. The measurement of transverse spring rigidity was conducted to verify the formula. The measured value differed from calculation results by about 9%.
