Scope
The purpose of this document is to provide the user with the procedures needed to properly assemble and disassemble the 50th percentile male Hybrid III dummy, certify its components and verify its mass and dimensions. Also within this manual are guidelines for handling accelerometers, repairing flesh and setting joints.
Rationale
The 1986 version of Engineering Aid 23 focused on differences between the Hybrid III and its predecessor, the Hybrid II dummy.
The 1998 revision of EA-23 removed the differences between the Hybrid II and Hybrid III, as most users had experience in using the Hybrid III. Instead of presenting two variations on the calibration procedures that were included in the 1986 version, only the currently accepted practice is listed. It included modifications which are based on many years' experience with the Hybrid III, and addresses changes incorporated into the dummy. The most significant differences result from some changes in the Hybrid III dummy. One change now calls for using feet with a 45 degree range of motion rather than 30 degrees; the feet also have a prescribed force-deflection characteristic. The other major change is a redesigned upper femur, which makes the hip joint range of motion more symmetric and biofidelic, and also prevents metal-to-metal contact between the hip bone and the femur. These part changes require additional procedures to ensure the proper range of motion at the hip joint.
SAE J2856 replaced EA-23 in 2009. In addition to the format change and the correction of typographical errors, the following corrections were made to this Information Report:
