Implementation of one kind of side impact method for child restraint system based on sled test

摘要

Although accident analysis shows that side impact accidents continue to be dangerous for children in cars, the majority technical regulations of Child Restraint Systems (CRS) are focused on the crash performance under the frontal and rear impacts and do not include a side impact test, the main reason is that no good method to test side impact performance of CRS has been agreed on yet in the world. In this paper one side impact test method based on double sled concept is presented and realized. And several CRS models are tested; injury response values are measured from child dummy. It is observed that the sled buck concept is repeatable and able to distinguish preliminarily between CRS models.
