Side Impact Test Results using

WS & ES2 in AE-MDB

Korea Automobile Testing & Research Institute

Eun-Dok LEE Ph.D.

Informal Group on Harmonization of Side Impact Dummies

9th meeting

Slide 2 of 21

Program Overview

• Assessment of WorldSID dummy in vehicle crash

environment.

• Test conditions

- AE-MDB 1,300kg, 50km/h

• Comparison of WorldSID 50th and ES2 dummies

- for Compact & Midsized vehicles (4 times)

- Injury parameters, Rib deflections etc.

Note : Test was conducted by a part of KATRI & HMC

WorldSID & PSI Joint Research program

Summary

• Thoracic Injury responses (e.g location of maximum Rib

deflections) of WorldSID and ES2 dummy are not

consistent with each crash test.

• This seems due to the differences of seating

position & posture, dummy heights etc

• After aligned with heights of rib locations, the location

of maximum rib deflection may consistent with two WS

& ES2 dummies It is needed to collect more crash test data and research to verify

this results
