Abdomen PC

Overview​

This test metric is defined for the EuroSID anthropomorphic test device (ATD), which incorporates three uniaxial force transducers in Y-axis direction and positioned within the abdominal cavity. These transducers are designed to quantify lateral loading of the abdomen during side impact events, providing critical data for evaluating localized force distribution and correlating with injury risk to abdominal organs.

Required Signals​

  • Abdomen 1 Force, Abdomen 2 Force, and Abdomen 3 Force (Y) in the EuroSID Dummy

Calculation​

  1. Filter all signals (CFC = 600)
  2. Sum the 3 force signals
  3. Calculate the peak of the sum of abdomen forces and corresponding time
  4. Compare to the IAV

Injury Criteria​

The EuroSID injury criteria for the abdomen is 2500 N. [2]

NCAP Combined Injury Rating​

The abdomen force metric is used in the NCAP side pole and side MDB tests for the ES-2re dummy.

Pabdomenforce(3+)=11+e(6.04044−0.002133∗F)(Equation 1)P_{abdomen force} (3+) = \tag{Equation 1}\frac{1}{1+e^{(6.04044-0.002133*F)}}
