HYGE
Crash Simulation Systems
Since
the first Hyge reverse accelerator system was developed in 1963,
more than 60 such facilities have been built worldwide. They have
been used in developing restraint systems in the automotive, aerospace,
rail and military industries. The success of this technique has
been based on four main factors:
- Reliability – just one major moving
part with minimal turn round time between tests
- Repeatability – within 2% between
firings, vital for restraint systems testing
- Accuracy – exceptional ability to
replicate actual vehicle crash test accelerations
- Flexibility – application ranging
from very low accelerations for rail vehicles to very high for
simulating explosive blasts.
The
HYGETM system
is designed to simulate the effects of a collision in an acceleration
rather than a deceleration mode. The HYGETM's
design provides extremely repeatable and reproducible acceleration
pulses, enabling accurate simulation and modeling of crash conditions
in nondestructive fashion. A given pulse can be accurately produced
on any HYGETM
system, enabling component suppliers and OEM manufacturers to
share testing programs and data interchangeably. The HYGETM
system has proven its repeatability over time. Systems over 40
years old routinely demonstrate repeatability of better than +/-2%.
HYGETM
systems are used by virtually all of the world's automobile manufacturers
to test passenger safety devices such as seats, seat belts, child
restraints, and air bags, as well as components such as door latches,
windshield mounts, and fuel tank mounts. HYGETM
systems are also widely used for aircraft safety tests.
We offer five standard HYGETM
system designs which can be tailored to meet your requirements.
The base system configuration are listed below. The size denotes
the diameter of the thrust piston.

The
Dynatest 500 has stroke length of 12 inches
(305mm) simulates the effects of a collision in either acceleration
or a deceleration mode. It is designed to test components such
as door latches, windshield, transmission, engine, fuel tank mounts,
body parts, etc.
The
6-inch HYGETM Vertical
has a stroke length of two (2) feet, It is designed for testing
small components or hand held devises.
The
6-inch HYGETM
Horizontal
has a stroke length of two (2) feet, delivering up to 64 g's on
payloads ranging from 150 to 600 pounds. It is designed for testing
components and small car bucks.
The
12-inch HYGETM
offers a stroke length of five (5) feet, and is capable of testing
complete vehicles as well as major subassemblies. Over 40 units
of this type have been installed around the world. Virtually every
major automobile manufacturer and many major suppliers own these
systems.
The
24-inch HYGETM
is designed for testing school buses and trucks, as well as seating
anchors in aircraft.
