The most common accident scenarios include a full frontal collision or a roll-over accident. When the cab is struck by an external object, its primary task is to transfer energy to the rear in order to maintain sufficient survival space inside.
At Volvo Trucks we test our cabs thoroughly in a series of sequences, including the front pendulum test. And all our cabs meet the Swedish cab strength standards - the toughest in the world.
Absorbing the energy of the impact
There are tremendous forces at work in the event of an accident. The force to which your body is subjected is likely to be at least twice the weight of your entire body. A person weighing 100 kg is exposed to a force equal to four tonnes when travelling at 50 km/h. That is why the cab interior needs to be energy-absorbent, in order to yield to the impact of the human body.
In all our cabins, the steering wheel and the dashboard are energy-absorbent, as are the trim panels at knee height. All upholstery fabrics are also made of flameproof materials.
In addition, interior accessories such as the microwave oven and coffee maker are designed to be firmly attached to the cab structure. This ensures that they stay in place in the event of a collision or emergency braking manoeuvre.
FUPS - protecting other road users
In a frontal collision, the truck will often wedge a car in a deadly trap. To prevent this and to maximise the effect of the car's own crumple zones, Volvo Trucks has developed the Front Underrun Protection System (FUPS).
FUPS is standard on the Volvo FH and Volvo FM models. Using a 200 mm deep crumple zone, penetration into the car's passenger compartment is considerably reduced. FUPS increases the survival rate of the car's passengers. Additionally the truck bumper is located at the same height as that of a typical car bumper, so that the car's deformation zone can be fully utilised.
