Durability Testing & Response Reconstruction

We specialize in reconstruction of dynamic multi-axis response of structures, systems and components in a laboratory environment for fatigue analysis, conformance testing and certification

Service Overview

We specialize in reconstruction of dynamic multi-axis response in of structures and units under test in a laboratory environment for fatigue analysis, conformance testing and certification.

Our combination of extensive hydraulic and electrodynamic infrastructure uniquely positions us to provide industry with accelerated full-scale fatigue testing, component fatigue testing, static testing, and shock and vibration testing.

Expertise

Durability testing

Durability testing (dynamic or quasi-static), of full-scale tructures (e.g. road simulators), sub-systems and components (e.g. springs, shaft steelwork).

Response reconstruction

Response reconstruction and laboratory test routine design (time waveform replication) of dynamic, multi-axial responses in laboratory test rigs.

Vibration Testing

Vibration tests: sine, sine-on-random, random, etc. | Shock tests: half-sine, terminal saw tooth, SRS, complex pulses, etc. | Static strength testing. | Automotive noise, vibration and harshness (NVH) testing.

Field measurements

Field measurements, fatigue and spectral and analysis to characterise the mission profile from field measurements.

Design of mission profile derived laboratory test routines.

Equipment and Software

Universal testing machines: 40 kN, 100 kN and 630 kN (Instron).
Servo-hydraulic actuators, ranging from 6 kN to 250 kN.
Large hydraulic servo-valves for high-speed testing.
PID servo-controllers (Kelsey K7500, Zwick-Roell Cubus, Instron Labtronic 8800, Moog).
280 bar hydraulic supply, 500 L/min maximum flow.
Variable pressure and flow rate hydraulic test bench (up to 90 lpm).
Electrodynamic shaker (100 kN peak load, 50 kN RMS load).
Slip table: ETS GT1000M (1000 x 1000mm).
