5、een 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
6、 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
7、 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 cont
8、act 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 I

They noted that a users manual would be helpful. In response, the SAE Dummy
37、 Testing Equipment Subcommittee of the Human Biomechanics and Simulation Standards Committee prepared a Users Manual which became SAE Engineering Aid 23, published in June 1986. It has since become the basis for manuals on the entire Hybrid III family of dummies. TABLE OF CONTENTS 1. SCOPE 72. REFER
