3 <strong>Crash</strong> <strong>Management</strong> <strong>System</strong> 21<br />

Volvo is completing similar crash tests against an 850 t heavy steel block barrier with an<br />

angle <strong>of</strong> 30°. This configuration can be seen in Fig . 3-26. The truck has a velocity <strong>of</strong> 30 km/h.<br />

This test corresponds to a 50 km/h crash into the rear <strong>of</strong> a trailer. Again the goal is to identify<br />

the energy absorption, cabin strength, cabin attachment and the evacuation behaviour <strong>of</strong> the<br />

cabin structure. In addition occupant injuries are evaluated [VTN09].<br />

Fig. 3-26: <strong>Crash</strong> configuration by Volvo [VTN09]<br />

For the FE simulations <strong>of</strong> the self-protection tests in this study, the tractor hits a semi-trailer<br />

with a velocity <strong>of</strong> 30 km/h and at an <strong>of</strong>fset <strong>of</strong> 50 % between truck and the trailer. The crash<br />

per<strong>for</strong>mance is evaluated by analysis <strong>of</strong> the intrusions and the energy absorption behaviour.<br />

The FE model configuration used <strong>for</strong> the simulations can be seen in Fig. 3-27.<br />
