Remarks: During the CLEVER project only the following three crash tests were performed. The aim of these tests was to validate the numerical simulation and to look for possibilities to improve the vehicle.
The tests proved that the concept allows a high occupant safety design and the structure of CLEVER is correct.
Frontal impact (according US-NCAP)
Test conditions: 56 km/h against a rigid wall; no offset
Dummies: Driver and passenger
Results:
- The frame of CLEVER was deformed as designed, we recognised no serious destruction.
- The cabin remained without major deformations, the acceleration was at an acceptable level allowing the restraint system to protect the occupants.
- The maximum intrusion in the cabin was so low that we had a really low injury risk for the legs of the driver.
- In total 8 Euro NCAP points were achieved in this test.
Improvements:
- Increasing the stiffness of the driver’s seat leads to lower movement of the seat itself. The kinematics of both occupants would be improved. This would result in lower injury risks for the driver’s neck and the passenger’s head.
- The front wheel swing arm collapsed and came loose. This problem will not occur on the standard solution because a cast construction instead of a welded aluminium construction will be used.
