test systems perform fatigue life, characterization and basic
static tests on a variety of materials to simulate combined
loading and strains experienced in actual service conditions.
Our modular test system approach uniquely
enables researchers to expand their system from an entry level
single axis actuator into a four channel system in stages that
match budget or research objectives.
The system includes a test table with
- 4 actuators matched to requirements.
- 2 load cells and stroke sensors.
- Power Packs
- High Resolution Dynamic Servocontroller
- Multichannel Test Software
- bath - saline at 37C
- Optional biaxial strain control software (requires camera).
Four actuators are arranged
90 degrees apart. Two master – slave actuators are on
one axis and two master – slave actuators are on the other
axis. The actuator pair operates in load, strain or position
control, ensuring sample center point can be maintained at 0,0
- which is critical in situations where video is used for real
time strain control.
The movie shows a
test system with four actuators and a large bath testing a large
sheet test sample. The actuators are controlled to produce equal
and opposite motion and loads on two axis perpendicular to each
other. Each axis can be controlled in load, strain or position
control. Systems are configured to match each customers load
and stroke requirements.
