Crash Test Dummy | I Didn’t Know That

throughout the world of testing there’s
always one guy that seems to take the
hit in the name of safety
he’s a crash-test dummy at a laboratory
in Holland they test them to ensure
their reactions are as human as possible
oh wow first up the head drop test
inside the head of three sensors for
measuring acceleration or deceleration
one for each direction a sensor in the
neck measures the forces on the dummy
the head is held by an electromagnet
when the button is pressed the current
is cut the deceleration the rate at
which the head slows when it hits is
measured in G the lower limit is set to
a 100 G at up limit is set to 150 G the
value we measured is 125 G so that’s
right in the middle so we can say that
the head has passed its certification
next the knee impact test a 5 kilogram
weight is dropped onto the knee to
measure the displacement ouch
here a new dummy is about to be hit full
in the ribs
he has three abdominal force sensors and
his shoulders rotate realistically to
expose his side where a human body would
break the dummy stays intact and
measures the damage in fact a dummy can
last for 20 years but it needs to be
recalibrated every few crash tests to
make sure it’s still accurate
lastly it’s time for the front or chest
test the kind of forces the dummy could
go through if it hit the steering wheel
if you try to push the dummy’s chest
with your hand you’d get about a
centimeter in with this test it’s
compressed more like 7 centimeters
nasty stuff but it’s these simulations
that save lives and this dummy is a pass
