The Collision Behaviour of a Vehicle When Considered as a Multiple Mass System 845023
When analyzing vehicle collisions and determining the impact
impulse or the energy balance it is usual to assume that there is a
single mass concentrated at one point in the vehicle. This method
of observation is in most cases not correct for loaded commercial
vehicles.
The behaviour of the individual masses was investigated in
various collision tests whereby the load consisted of gravel, steel
plates welded to the vehicle, belted and non-belted dummies or with
the vehicle unladen. In the displacement of the individual masses
in the vehicle the kinetic energy is partially converted to
deformation energy in the area of load compartment and load, into
potential energy and frictional energy. This relieves the impact
zone of the vehicle and the collision partner.
A participation factor is defined which makes it possible to
estimate to what extent the load mass or the occupant mass
influences the vehicle deformation.
