Abstract
An energy dissipation system for a frame of a vehicle includes a frame rail including a crushable region and a non-crushable region. An energy dissipation device includes an energy transfer portion arranged partially in the crushable region and partially in the non-crushable region and configured to move in response to a vehicle impact on the frame rail. An energy dissipation portion is arranged within the non-crushable region, connected to the energy transfer portion. The energy dissipation device includes a first region connecting the energy dissipation portion to the non-crushable region, and a second region connecting the energy dissipation portion to the energy transfer portion. The first region of the energy dissipation portion is stiffer than the second region of the energy dissipation portion.
