Results of Crash Tests According to the Ece/Grcs Regulation Proposal Concerning 50km/H Frontal Impact Against the Rigid 30Md Barrier 856059
The Federal Highway Research Institute (BASt) has advised the
Federal Minister for Transport on drawing up a draft regulation for
the protection of vehicle occupants in a frontal collision. This
draft regulation provides for a collision between a vehicle and the
rigid 30° barrier at 50km/h.
In determining the test criteria, a number of questions had to
be answered: Which calculatory and influencing possibilities are
there in the application of the head protection criterion? How can
the head contact be clearly determined? What spreads do the
measured values for the dummy demonstrate under the same test
conditions, and must these be included in the draft regulation? How
frequently does submarining occur and how can submarining be
measured? What other regulations can be covered by the global test
proposed by this draft regulation? Do small passenger cars
currently on the market already fulfill these test conditions?
Results of the following studies by the BASt concerning these
aspects are introduced in this paper: Theoretical studies in the
"Application of the Head Protection Criterion"; Practical
applications (eight crash tests) on the topic "Variance of the
Measured Values"; Accident data analysis on the topic
"Frequency of Submarining"; Trolley tests on the topic
"Determination of Submarining by Measurement"; 10 crash
tests using subcompact passenger car; and inclusion of other ECE
regulations in the global test.
The draft regulation is introduced and critically assessed.
