Název v původním jazyce

Stress and deformation response of a car safety frame on static and impact loading

Popis výsledku v původním jazyce

The safety frame is the main element of passive safety for most racing cars. Till now the frames stiffness is investigated only on the basis of static loading tests, which are not able to take into account the dynamic effect of the high speed impact dueto the car collision. For more correct frame safety analysis the dynamic impact loading simulation is necessary. The influence of the impact velocity on the frame stiffness, stress and deformation has been studied and comparison with results obtained forthe static loading has been performed. The static and dynamic loadings exhibit very different stiffness, deformation and stress time courses in the time just after impact. Later the differences are not so big. Furthermore the car rollover has been modeled as a dynamic impact problem for the impact velocity 20 km/hour. A relative good agreement with corresponding prescribed static test has been achieved with exception of the time period close to impact. The explicit version of the finite
