Analiza impact lateral - Virtual crash

The expertise of the criminology department process by definition is the act by which shall be carried out scientific research sampling materials for the identification of welfare, objects, substances, phenomena or events, establishing certain properties, changes in shape, appearance, content or structure, as well as the mechanism for producing them. Problematic and multidisciplinaritati examinations in the houses of criminal investigations shall include in their entire and purely technical aspects of which is inseparable linked.

On the basis of her character interdisciplinary criminology department uses both some specific methods and methods of other sciences. Between the specific methods may be remembered those used for discovery, mounting, raising, the examination, interpretation of traces and the means of proof, for identification purposes, for carrying out the examinations or for carrying out the comparative trials. In addition to the specific methods, criminology department uses and methods of other sciences such as: spectroscopy, gas chromatography, tests of color, photogrammetry, for calculation, etc..

Within the recovery using specialized programs, carried out within the framework of the institute and laboratories, dynamic and kinematic analysis of the road event is not carried out outside the process of interpretation of all created. Such trajectories resulting from the simulation must comply with those printed of motor vehicle tires or damaged sub-assemblies which, as a result of the deformation, comes into contact with the Carriageway. Must be analyzed also the position of the traces of the ground, the films of paint, broken glass, the traces of liquid or other fragments of the damaged sub-assemblies which, together with other suffixes, configure both the layout of the site impact and post-collision trajectories, items required an examination criminal investigations which constitute the basis for further analytical determinations.

For example, according to the nature of the traces of tire (braking or wheel slippage), resulting from the examination by the judicial expert photo or even on the spot, in view of a specific system of deceleration of the vehicle which has printed. Also, the interpretation of traces of collision, it is important to establish mutual positions of the vehicles at the moment of impact or for the choice of an appropriate calculation as regards the fixing of the gear on the impact of motor vehicles by a uniform methodology used at international level.

This methodology involves both an analysis of trajectories, and an analysis of the residual registering strains of the vehicles. The first of these is therefore based on the interpretation of the traces of the above mentioned and lead to the reconstitution of trajectories of the vehicles involved in the collision, the second involves either quantification of deformation energy by means of an analytical calculation either by a comparative examination with catalogs containing vehicles damaged in the collision magnitude known. Observe and thus in this respect comparative examination of its applicability.

Presented as these aspects can be given some conclusions concerning the main objectives which may be laid down in the framework of expertise criminal investigations of the accident of traffic:

• Establish status as a matter of fact;

• reconstitution of trajectories of motor vehicles involved in an accident;

• residual analysis of registering strains;

• determine the impact;

• establish the relative position of the vehicles or between the vehicle and the victim (in the case of accidents in which they are involved pedestrians);

• establish travel speeds;

All these objectives can be solved only after an activity for the interpretation of all created in the event and recorded on the spot. Once solved these aspects, with a view to the establishment by the judiciary of guilt, it is necessary to finally, and an analysis of the event, cinematic road that an analysis of the previous phase of collision. In this shows if the event could be avoided and under what conditions, so that they can be put in the report of the causal link between the action or inaction of the participants at the event and the outcome of the product. As such, the objectives of which concluded in general such specialized work are:

• determining the possibilities of avoiding the production;

• establish the cause of the accident
