ON LOADING OF A TANK CAR SHELL UNDER HYDRAULIC IMPACT

Abstract

A mathematical model of shunting collision of a tank car is offered, taking into account the possibility of installing automatic couplers with absorbing devices of various types, fluctuations of transported liquid cargo in tank shell at incomplete filling and the likelihood of hydraulic impact. Calculations resulted in proposed choice of rational parameters and of a shape of tank shell bottom which allow increasing carrying load and volume of the tank shell. Scientifically sound limits for impact speed were determined for certain types of shunting operations with tanks to ensure safe working conditions, minimization of environmental risks.
