In recent years, the specification of a Side Impact Moving
Deformable Barrier (MDB) has been in discussion internationally.
This paper describes the results of our investigation and
examination concerning the MDB specification, based on current
Japanese models. The paper describes the following.
1) The investigation of the dimension of passenger cars in the
Japanese market to determine the average of car front-end dimension
characteristics.
2) The analysis of force distribution on the rigid barrier in a
frontal barrier impact test of typical Japanese passenger car
models by using FEM.
3) Comparison of test results between a car-to-car test using
the passenger car with average front-end characteristic as a
striking car and a MDB-to-car test under ECE R95 test
condition.
As the results of these studies, we summarize the necessary
considerations to represent real vehicle for the design of the MDB
face for a future internationally harmonized procedure of side
impact testing under consideration by the Harmonization Research
Activity (""IHRA'') of Side Impact Test
Procedures.
