Ecological Systems and Devices Annotation << Back A common approach in defining the parameters of colliding bodies collisions A.N. Karelin, E.N. Karelin In this paper, the formation of the general concept of calculating the parameters of colliding bodies through a variety of methods and approaches. In practice, expert activities to support certain findings necessary to carry out verification calculations for emergency situations. Some cases do not fit the typical description, and then you need to use special methods of calculation. Key words: modeling; the lack of initial conditions; the colliding objects; road accidents.
