The study of the dynamics of mechanical impact of solid deformable bodies is an urgent problem in mechanics. This problem is associated with the strength calculations of machine parts and mechanisms. The most difficult case is the strength calculation under shock and vibration loads. Exact mathematical equations are obtained only for simple structural elements of machines: balls, rods, plates, beams, etc. The mathematical description of the dynamics of elements of machines of complex shapes under impact conditions is seriously difficult. A method of dynamic strength analysis of machine parts using the Hertzian contact theory is proposed. For the cases under consideration, the impact velocity of two bodies does not exceed 100 m / s.
