Mathematical modeling and dynamical studies of
railway vehicles considering the special features
of their safety means under impact loads
A high-speed passenger locomotive ?P20
Developed and patented in Ukraine design of an
energy-absorbing device
A principally new design of an engine-driver cab
Simulation of a stressed-strained state of the
crash element on impact
Stressed-strained state of the crash element and
cab framework elements on impact

• Comprehensive research on the finite-element
  simulation of nonlinear contact interactions
  between elements of a front part of an electric
  locomotive and the firing-pin is carried out
  considering
• geometrical and physical non-linearities
• dynamical steel strengthening in accordance with
  impact velocity
• failure of the crash elements of a passive safety
  system on impact

M80 t V36 km/h
