Fully dynamic approach to calculation
A fully dynamic approach to calculation
should not only determine the different loads assumed by the securing devices
until equilibrium with the external force, but should also identify the
additional forces which are required to bring a cargo unit which has started to
move/deform back to a standstill. Such an approach can virtually only be implemented
with the assistance of a simulation which models the limited time period of the
critical driving situation. The effects of buildup phases and of pitching and
rolling oscillations outlined in section 1
can be taken into account in this way.
One essential item of information from
typical, calculated cases is the magnitude of the stated additional forces and
their dependency on the parameters involved, such as friction coefficients and
the elasticity of cargo securing devices. Evaluating such items of information
should allow for all-inclusive allowances to be defined and recommendations for
laying out securing arrangements to be drafted.
