CALIBRATION AND CERTIFICATION

CALIBRATION AND CERTIFICATION

We certify the dummy using the calibration test equipments in our test house. The test equipments and test method are specified with CFR 49, Parts 572. We also carry on our original test to check if the parts have high quality, that is enough durability, supplemental check for neglected performance, and of course for repeatability/ reproducibility.

Neck Flex/Extention Test System

The neck for ATD consists of aluminum disk plate molded with rubber and wire cable.
You can control neck behavior at some extent by tight/loosen the cable torque.
The neck test is required for a variety of items, not only its performance (angle, moment etc.)
but also test conditions (speed, deceleration etc.).
Specification Based on Title 49,CFR Part 572 and TRIAS
Pendulum 3×4 inch×0.185 inch Thick,1.835mm Length
Pendulum C.G 828mm
Suspension system Electrical Winch

Thorax Impact Test System

The thorax behavior is mainly effective by its rib performance in this calibration test.
The rib for ATD consists of steel with damping material.
Of course not only the ribs but also the lumbar spine, chest jacket and test condition is influenced for this test results.
The test impact probe should be changed for each different dummy.
Specification Based on Title 49,CFR Part 572 and TRIAS

Knee Impact / Share Test

The knee of ATD consists of Aluminum bone, rubber flesh and PVC skin.
The rubber performance is the most important to the test results,
but also the flesh thickness/hardness and rigidity of test equipment should be under consideration.
Specification Based on Title 49,CFR Part 572 and TRIAS
Suspension Wire suspension,1800mm Length
Release By hand
Measuring speed Photo sensor
Installation size 800㎜(W)×2000mm(L)

Needed to change probe which is required by regulation and also
wire set which has different wire pitch to adjust probe suspension.

Hip Joint Test System

The pelvis for ATD consists of aluminum bone, urethane flesh and PVC skin.
And bronze femurs are assembled. Femur has urethane bumper to prevent the metal contact between femur and bone.
This calibration requires the behavior of pelvis bending, which is related with PVC thickness/hardness and interference between femur (bumper) and pelvis.
Specification Based on Title 49,CFR Part 572 and TRIAS

Torso Flexion Test

Some of the dummy parts relate to this test results, performance of lumbar spine and abdominal insert, interference between chest jacket and pelvis. And this test is not required for H-Ⅲ50th percentile male dummy.
This test requires the behavior of assembled dummy performance in upper torso bending.
Specification Based on Title 49,CFR Part 572 and TRIAS
Pull speed 0.5~1°/秒
