CUSTOMIZED LUMBAR SPINE RESPONSE FINITE ELEMENT MODEL FOR CRASH TEST DUMMY AND METHOD

摘要

A customized lumbar spine response finite element model for a lumbar spine of a crash test dummy is disclosed. A method of creating the customized lumbar spine response finite element model for the lumbar spine of the crash test dummy includes the steps of identifying two borderline sets of test data profiles for the lumbar spine that match with extreme test data profiles of the lumbar spine of the crash test dummy, varying material properties of the lumbar spine 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 extreme test data profiles, and creating a single lumbar spine response finite element model for the lumbar spine of the crash test dummy with a user-defined input parameter for the lumbar spine response finite element model that defines a customized response.
