| LX and FLX |
LX [Lower Extremity] was designed, developed and manufactured
under funding from the NHTSA. LX incorporates important structures
in the human lower leg such as the Achilles tendon, and the two joints
in the ankle. Compressive deformation characteristic of the tibia is
modelled by the introduction of a deformable elastomeric puck at the
top of the tibia. The LX can be bolted on to the knee of the Thor or the
H-3 50th male dummy. LX is shown on the left in the picture at the
top of the page. Please click on the picture to see a bigger image.
FLX [Female Lower Extremity] was designed, developed, and
manufactured under funding from the NHTSA. FLX too incorporates
the Achilles tendon, the two ankle joints and an elastomeric puck at
the top of the tibia. The FLX can be bolted on to the knee of the 5th
percentile H-3 or Thor female dummy. FLX is shown on the right in
the picture at the top of this page. Please click on the picture to see a
larger image.
Both legs are instrumented with the following sensors:
1. Upper tibia load cell, 4 or 5 axis
2. Lower tibia load cell, 4 axis
3. Tri-axial accelerometers on the foot
4. Bi-axial accelerometers on the tibia
5. Uni-axial load cell in the Achilles tendon to measure compressive
load.
