Comparison tests on full crash test facility and hyge sled test

facility in the frame of Regulation ECE R16

Tests parameters

• Tests according to the provisions of regulation ECE R16

• 3 points inertia reel safety belt with load limiter

• Comparison on safety belt load and thorax and pelvis excursion

Use of 3 different crash test facilities

• full crash test facilitySled mass M=1200 kg - Acceleration 50 m et 25 m

• full crash test facility with a sandows sledSled mass M=400 kg - Acceleration 12 m

• hyge sled test facility Sled mass M=1700 kg

full crash test facility hyge sled test facility full crash test facility with a sandows sled

Acceleration distance: 50 m 25 m 12 m Sled mass : M=1200 kg M=400 kg M=1700 kg

Synthesis

•Theorically, there is no difference between the full crash test facility and the hyge sled test facility on the thorax and pelvis displacement and on the load of seat belt.

•The ratio dummy mass and sled mass have influence on the results.

Conclusion

Regulation evolution

– Let the choice of using the hyge sled test facility

– The sled used for testing shall be precised (mass,…)

Conclusion•First step:

Annex addition in the following regulationsECE R14, ECE R16, ECE R17, ECE R21, ECE R44, ECE R94, ECE R95

•Second step:Modification of the regulations
