Headform Development for Neck Calibrating Tests of the SID-IIs Side Impact Dummy 2001-01-0121

The SID-IIs side impact dummy is a newly designed dummy as an anthropomorphic test device for small size person to be used in side impact crash testing. The head and neck are one of the key components for SID-IIs dummy designing, manufacturing, and testing. This paper is focused on the development of a Headform to be used for neck calibration of the SID-IIs side impact dummy.
It will be very difficult in neck calibration measurement of the SID-IIs dummy if its head is used for the test directly. The Headform is one of the methods to solve this problem. However, the Headform must be consistent in achieving equivalent functional performance as the dummy head and associated physical properties. A 3-D head model has been developed for obtaining initial basic information. The offset can be controlled within 3% during the engineering design of the Headform.
The neck dynamic test has been done before the Headform test. The neck movement has also been analyzed by using the high-speed video system at testing. More tests have been conducted to evaluate the Headform performance at various calibration laboratories. Test results indicated that the performance of the Headform is consistent with the design concept of SID-IIs Headform.
Based on the test results analysis, the new Headform has yielded stable and repeatable results to match the calibration requirements. The Headform can therefore be used for the neck calibrating tests of the SID-IIs side impact dummy.
