Fatigue Testing
Servo-driven fatigue systems for high-cycle and low-cycle work — a single-axis machine for coupons and components, and a multi-axis rig that loads a part along several axes at once with a programmable phase shift between them.
- Frequency
- upto100 Hz
- Load
- upto500 kN
Two machines, one control system.
The single-axis machine drives one electro-linear actuator through a 60 mm stroke — coupons, components and the eight-station pulsatile rig for vascular stents. The multi-axis rig runs several Electro_Ax servo-hydraulic drives at once, in linear, parallel or orthogonal layouts, each phase-shifted against the master axis. Both are programmed from the same Dyna Desk – Test Bench software and the same Advanced Wave Maker.

Load accuracy is verified to ASTM E4, ISO 7500-1, EN 10002-2, JIS B7721 and DIN 51221; strain to ASTM E83, ISO 9513, EN 10002-4 and BS 3846.
Load cell accuracy is ±0.5% of indicated load or ±0.005% of load cell capacity, whichever is greater.
The 500 kN figure is the ceiling of the Electro_Ax servo drive on the multi-axis rig. Capacity on either machine is configured to the application — send us the loading and we will size it.
Built for the cycle after the millionth.
A load cell that subtracts its own inertia, a drive with no valves to wear, and limits that stop the frame before the specimen does.
Advanced Wave Maker
Build the loading history stage by stage — blocks, ramps and holds in sequence, saved as a method and repeated exactly.
Four control modes
Load-controlled high-cycle and strain-controlled low-cycle work run on the same frame, switching mode mid-test where the method calls for it.
Fatigue-rated load cell
An accelerometer on the load axis measures the inertia of the moving mass and subtracts it in real time. That is what keeps the load honest at 100 Hz.
Multi-axis with phase shift
Each axis holds its own closed-loop PID and can be offset in phase from the master, so a part sees the combined loading state it meets in service.
No servo valves
A servo motor and variable-speed pump replace the valve block, power unit and piping. Energy falls by up to half, hydraulic fluid by up to 90%.
Sample protection
The crosshead moves to keep force on a gripped specimen inside a set threshold, so the sample is not deformed while it is being clamped.
Follow Me and Safe Jog
Push or pull the upper grip and the crosshead follows; harder means faster. During positioning it stops instantly on sensing force.
Bio-Bath at 37 °C
Implants cycle in a temperature-controlled saline bath under closed-loop control, with the fixture raised out on the crosshead for inspection.

Configured around your specimen, not the average one.
A result is only as good as the grip that holds the specimen, the extensometer that reads its strain, and the environment it endures. All three are specified alongside the machine, so the load path is right from the very first test.
Fixtures
A fixture for the part, not a compromise.
Grips and holding fixtures across the industries we serve, including the medical set — ASTM F2077 for intervertebral fusion devices, ISO 7206-4 and -6 for hip stems, ASTM F1800 for knee implants.
Bio-Bath
Body temperature, under closed-loop control.
A clear polycarbonate saline bath for implant work, running phosphate buffered saline or an equivalent, with temperature recorded alongside the test results.
Eight-station pulsatile rig
Eight stents, one run.
A circular mounting of high stiffness and low mass, fatigue-rated load cell on each station, for diameter-control pulsatile durability testing of vascular stents to ASTM F2477.
