Japan Automobile Research Institute, lnc. (JARI) and Japan Automobile Manufacturers Association, lnc. (JAMA) have been making continuous effort to study on the following themes since 1985 in order to examine the side impact test methods.

Analysis of side collision accidents in Japan:

Analyze the data collected on side collision accidents

Evaluation of energy-absorbing units of MDB:

Investigate average specifications of the Japanese domestic cars and the characteristics of energy-absorbing units made by JARI/JAMA

Examination of full scale test methods;

Review such factors for occupant injuries

Examination of component test methods:

Perform numerical analysis simulations
Study the various causes of occupant injuries

Comparison tests of side impact dummies:

Compare SID(NHTSA) dummy and EUROSID dummy

This report describes part of our research. It deals with the results of our development efforts of making energy-absorbing units of MDB based on the average dimensions and characteristics of the front end of Japanese domestic cars.

Specifically, this report explains in detail the development process, static and dynamic characteristics, dependency on impact speed and crab angle, etc., and also the results of full scale test using the energy-absorbing units.
