| Abstract: | In an accident. the front and back of body-
work model can adsorb impact energy on condition that
the internal space of it has no distortion. Based on finite
element LS-DYNA program, this paper has analyzed the
model of additional mass attaching to a single section, the
model of additional mass attaching to two sections pro-
portionately,and the model whose front wall thickness is
changed. According to the result, the problem is discussed
of how to increase the amount of impact energy of space
absorbed by the impact energy of front and back, with the
internal space unchanged. |
