Customized neck response finite element model for crash test dummy and method

A method of creating a customized neck response finite element model for a neck of a crash test dummy, said method comprising the steps of:

• setting a D-plane rotation between a maximum value and a minimum value of certification corridors for the crash test dummy;
• identifying two borderline sets of test data profiles of the neck that match with certification test data profiles for the neck of the crash test dummy;
• varying material properties of components of the neck for the crash test dummy;
• defining a mapping function to adjust the material properties and allowing intermediate sets of the test data profiles to be interpolated from the certification test data profiles;
• creating a single neck response finite element model for the neck of the crash test dummy with a user-defined input parameter for the neck response finite element model that defines a customized response;
• and
• varying finite element contact algorithm parameters of the neck response finite element model for components of the neck.

A method of creating a customized neck response finite element model for a neck of a crash test dummy, said method comprising the steps of:

• setting a D-plane rotation between a maximum value and a minimum value of certification corridors for the crash test dummy, wherein the D-Plane rotation is a default value corresponding to an average value of neck pendulum extension certification tests for the neck;
• identifying two borderline sets of test data profiles of the neck that match with certification test data profiles for the neck;
• varying material properties of components of the neck;
• defining a mapping function to adjust the material properties and allowing intermediate sets of the test data profiles to be interpolated from the certification test data profiles;
• and
• creating a single neck response finite element model for the neck of the crash test dummy with a user-defined input parameter for the neck response finite element model that defines a customized response, wherein the customized response is equal to a D-plane rotation peak at a certification level for the neck.
