Modelling and investigation of car collisions

While investigating collisions with immovable obstacles it is necessary to assess the place of contact, its character and the speed of vehicles before the contact. These parameters depend on the obstacle. The most common cases were analyzed in the article: collision with an immovable obstacle which deformed only a part of the fore of vehicle (collision with a tree, a bollard, etc.); collision with an immovable obstacle which deformed the whole fore of vehicle (collision with a wall, etc.).

Evaluation of car accident parameters during collision

According to he literature source [5], almost 47–52% from all carcrashes make collisions of cars. So it is possible to conclude that almost each second a carcrash is a collision. One of the most important parameters that should be determined during carcrash investigation is the car speed before the accident. Calculation of the parameters in various situations differs. The experts performing the investigation work of car crashes improve or create carcrash investigation methods in various cases. The methods of speed determination before crashes arc presented in these cases: direct collision, when cars move one after another, direct sided collision and sided sliding collision as well.
