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 child dummy is seeing increased use in car crash testing for safety reasons. A neck of the child dummy is one of the key components for dummy design, manufacturing and testing. The testing corridor would affect the all of the procedure for the neck. This paper would discuss the testing corridor for neck calibration of the child dummy. The testing corridors should be come from biomechanical results and combine with the material property. The paper has reviewed the research result and described the dummy neck of Six-Month, Twelve-Month, Eighteen-Month Old Infant (CRABI); Three-Year Old and Six-Year Hybrid III Child (Hybrid II Child dummy will not be discussed in the paper). A series of testing has been done for finding out corridors of the neck pendulum calibrating tests. It is difficulty to match the human corridors of crash reaction. There are several methods to approach the child neck corridors such as change design, adjust testing parameter and so on.
