- Slides: 7
Comparison tests on full crash test facility and hyge sled test facility in the frame of Regulation ECE R 16
Tests parameters • Tests according to the provisions of regulation ECE R 16 • 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 facility Sled mass M=1200 kg - Acceleration 50 m et 25 m • full crash test facility with a sandows sled Sled mass M=400 kg - Acceleration 12 m • hyge sled test facility Sled mass M=1700 kg
Comparison of the maximum Thorax and Pelvis excursion for the 3 tests facilities full crash test facility hyge sled test facility full crash test facility with a sandows sled Acceleration distance: Sled mass : 50 m 25 m M=1200 kg 12 m 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 regulations ECE R 14, ECE R 16, ECE R 17, ECE R 21, ECE R 44, ECE R 95 • Second step: Modification of the regulations
