18.104.22.168. Deformation zone
To reduce salon damage, forward and back frames which are deformed at blow are developed and effectively absorb/disseminate energy of collision.
At moderate head-on collisions in a zone of the amplifier of a bumper the blow dissipates to forward lateral frames and elements of a forward suspension bracket.
|Fig. 8.4. Zones of deformation of a body: 1–energy of collision; 2–forward amplifier of a bumper; 3–forward lateral frame; 4–forward cross-piece; 5–caisson; 6–lateral longitudinal beam; 7–lobby In-shaped
If collision occurs close to salon, energy of blow dissipates lateral longitudinal beams and forward B-shaped frames through a caisson, reducing blow on salon (fig. 8.4)
