| Outline of Final Research Achievements |
Automobile collision safety for the accident between the vehicles at the first collision has advanced by experimental, computational and theoretical evaluation. For more improvement of the collision safety, it is necessary to understand the automobile motion after primary collision to protect the driver, pedestrian and worker from another accident occurred by subsequence collision.
In this study, in order to clarify factors, which affect the automobile motion after side collisions, the motion evaluation of the automobile subjected to side collision was investigated by carrying out model collision tests, and fundamental analyses.
