The document discusses key design elements that provide safety in vehicle body design. It notes that vehicles should have a deformable front structure to absorb impact energy, a deformable rear structure to safeguard passengers and fuel tank, and properly designed side structures to prevent door openings during a crash. It also emphasizes the importance of crumple zones to dissipate energy gradually according to Newton's first law of motion and reduce internal organ injuries during accidents. Finally, it states that a front engine location is generally safer for passengers compared to a rear engine configuration.

1. Design of the Body for Safety
1. Body over frame structure
2. Uni body structure.

2. Cont..
Avoid sharp patterns, edges and projected elements.
External parts like door handles, mirrors, control knobs, etc.
To reduce pedestrians injury
Reduction of aerodynamic drag & noise.

3. Necessary requirements for a safe
vehicle body
1. Deformable front structure to absorb the kinetic energy
2. Deformable rear structure to safeguard rear passenger and fuel tank.
3. Properly designed side to prevent doors from opening due to crash.
4. Properly designed of roof structure for rollover protection.
5. Properly designed restraint systems

4. The sequence of energy dissipation and
speed reducing technologies
Crumple
Zone
Seat Belt Airbags

5. Safety System
1.Passive safety help to reduce the effects of an accident
2.Active safety help to prevent an accident

6. Crumple Zone for Safety
Newton’s first law states that an object in motion will stay in motion
If a vehicle is going 60 kmph, the bodies inside are also moving in
the same speed.
Even after a human body comes to a stop in an accident, the
internal organs continue to move.
Often causing serious injury to internal organs or death.

7. Engine Location
Front engine
=> Passenger safety point of view front engine more suitable
Rear engine
=> Giving them better grip of the road.
