GUIDES FOR SPECIFICATION AND DESIGN OF THE BODIES OF URBAN RAILWAY-VEHICLES

Taking a survey of the vehicle equipment, installations and operating conditions with respect to shunting and accidents caused by collisions of different kinds of urban railways as a basis, a computer model was developed to calculate objective and comparable data regarding the collision energy of vehicles with partly plastic and partly elastic deformations. It was possible to derive a simple computer programme from this model which can ascertain the spring excursion and plastic deformation distance of the front section of the vehicle. It could be shown that with most modern urban rail vehicles the valid level (determined in 1970) of forces which vehicle bodies have to sustain without deforming to obtain approval could be considerably reduced. This is made possible on account of the substantial progress which has been made in constructing light vehicles and in the amount of energy which can be absorbed by the couplings.
