Abstract
EN: Abstract. Purpose. Provision of strength and durability of the main structural element of DPKr-2 diesel
train - the leading car body. Methodology. A spatial solid-state 3-D model of the body is built and
durability calculations are carried out concerning action of loads stipulated by regulatory documents
operating in Ukraine. In particular, the following main estimated modes are considered: mode 1 – a
notional safety mode which takes into account the possibility of considerable longitudinal forces arising
during shunting movements, transportation and accidental collision; mode 2 – an operational mode which
takes into account forces acting on a train during acceleration to constructional speed, coasting or braking
from this speed while passing a curve. Results. Based on the results of theoretical and experimental
studies a conclusion has been made that the leading car body construction of DPKr-2 diesel train meets the
requirements of regulatory documents regarding strength and durability. Practical relevance. A complex
of calculation and experimental work concerning assessment of stress-strain state of the leading car body
of DPKr-2 diesel train under action of design and operational loads allowed the creation of construction
which meets not only operational requirements but also strength and durability ones.
