CONSTRUCTION CATEGORIES CRASHWORTHINESS OF RAIL VEHICLES. CONSTRUCTION SCENARIO FOR COLLISION
Through determined and assessed the ments for resistance to impact, it is necessary to establish the scenarios for impact in terms of the speed of the collision, the type and mass of the potential obstacles. To this end, the mechanical structure of vehicles shall comply with the ments to the construction of a railway vehicle EN 12663-1:2010: Railway applications - Structural ments of railway vehicle bodies - Part 1: Locomotives and passenger rolling stock (and alternative method for freight wagons) (Railway engineering. ments for the construction of a railway vehicle part 1 Locomotives and passenger rolling stock (alternate)) and to ensure the protection of the occupants in the event of a collision, providing a means for:
— limitation of the deceleration,
— maintaining survival space and the structural integrity of the occupied areas,
— reducing the risk of on top of each other wagons,
— reducing the risk of derailment,
— the limitation of the consequences of an impact to an obstacle on the tracks
The publication will be dealt with the following four basic scenario of collision:
— stsenariy 1: a frontal collision between two identical units.
— stsenariy 2: a frontal collision with a boxcar.
— stsenariy 3: collision on a level crossing unit of a large motor vehicle.
— stsenariy 4: collision of the unit with a low obstacle (such as a car of the railroad crossing, animal, rock, etc.).
These scenarios are described in table 2 in section 5 of the standard EN15227 2008.
