Damper Durability Test Systems
Subject single or multiple damper specimens to millions of durability cycles, or run short bursts of high-performing cycles to measure damping characteristics. MTS damper durability systems combine highly stiff, self-supporting bases to withstand high inertial loading and selectable three-stage servovalves to perform high velocity durability testing on even the largest dampers and struts.
Applications
- Durabilité
- Caractérisation
Test Specimens
- Amortisseurs
- Bielles
Key Product Features
Versatile
Models 850 & 852 deliver the force required for multi-specimen durability testing while supporting an array of optional hardware for a wide variety of performance testing

-
Servovalves (high and low flow modes): Achieve higher-precision in low-velocity tests while in low-flow mode with the addition of secondary servo valves.
-
Custom Accumulation: Increase system performance with additional accumulators. System can be customizable to meet unique testing needs.
-
Multi-specimen Fixtures: Enable testing of up to 8 specimens simultaneously. Individual force transducers for each specimen are used to provide accurate data acquisition
-
Side-load Actuators: Simulate real-world loading conditions by providing an adjustable lateral force on damper test specimens.
-
Environmental Chamber: Test dampers in real-world hot and cold conditions with an environmental chamber mounted in the test frame.
-
Water-jacket Cooling: Reduce testing downtime by keeping dampers within a test specification’s required temperatures ranges.
-
Vibration Isolation: Reduce force transmission into the floor and allow test systems to be installed into facilities sensitive to vibration.
-
Mud & Slurry Simulation: Simulate testing dampers in real-world muddy conditions. Regulate the amount and consistency of mud slurry with this self-contained mud-slurry option.
ISO 13849-compliant MTS damper test systems employ a certified, safety-rated Programmable Logic Controller (PLC) to manage all safety functions and subsystems, including:
- Safe Speed
- Safe Isolation / Safe Power Off
- Three-position mode switch (Off / Low / High)
- Safety-rated valves
- Test Area Enclosures
- E-stops & Station stops
