Automobilių susidūrimų tyrimas, taikant judesio kiekio ir energijos tvermės dėsnius

Abstract

In partical cases it is difficult to establish real post - accidental automobile parameters during the investigation of collision results (e.g., in the presence of human losses). Not always there renain sufficient evidences for the evaluation of such parameters and witnesses are often subjective or purposefully misleading. The theoretical method is the only possible way of establishing post-accidental automobile parameters. This work shows the use of well known laws of quantity of motion and of conservation of energy in research of automobile collisions. It shows that parameters of automobile motion before and after a collision can be established by using the methods under research. In parallel, the mathematical expressions (first presented by N. M. Kristi [1]) are demonstrated for establishing the velocity of automobile motion in some cases of the collision mechanism. The method presented was used many times in the examination of accidents for establishing the parameters of automobile motion during the moment of collision and after it till the end of the accident. Practical application of collision research methods for establishing parameters is demonstrated by one concrete example.
