Neck Test 2 (H28625-H28628) Dummy channels according to SAE J211.

Wayne State University Tests (H28631-H28641)

Impact forces and accelerations at CFC 1000 Hz, and Dummy channels according to SAE J211.

Heidelberg Tests (H28642-H28648) Impact forces and accelerations at CFC 1000 Hz

(according to SAE J211). For comparison to response requirements the data

was filtered using a 100 Hz FIR Filter.

The data presented gave plate loads and accelerations. The loads were corrected to compensate for inertia by using the following equations over the whole time span (after finding time 0 according to maximum loads).

Fe = Fi – (ma)plate

Example: Fshoulder = 8443.32 N

ashoulder plate = 44.88 m2/s

Mshoulder plate = 2.62 kg (mass of the plate + mass of bolts)

Fe = 8443.32 – [(2.62)(44.88)] = 8325.73 N
