Operational strength and fatigue life testing laboratory
The test laboratory has a universal electro-hydraulic loading system for static and fatigue testing of structural components and material samples. We specialize in testing welded structures. We also deal with increasing the fatigue life of welds.
WE OFFER
- Fatigue and static testing of materials, structures and contraction assemblies
- Low and high cycle fatigue testing including elevated temperature testing
- Fatigue testing of thin-walled welded sections of bus and trolleybus bodies
- Fatigue testing of structural nodes for rolling stock according to the relevant standards, including welds of higher thicknesses
- Tests of damping properties of insulators
- Increasing the service life of welds using HFMI technology
- Fatigue life calculations including vibration fatigue with nCode software
- Measurement of common physical quantities
- Measurement of static and dynamic operational loads and structural deformations
- Extensive temperature measurements
- Highspeed thermal imaging and other activities

LABORATORY EQUIPMENT
The key equipment of the testing laboratory is the INOVA electro-hydraulic loading system, which enables multi-channel static and fatigue loading, including measurement of deformation, displacement and acceleration.
To increase the lifetime of welds, we have HiFIT equipment.
Software equipment for life evaluation consists of nCode, Rifest and TestControl systems.
PULSE system for measuring dynamic phenomena, vibration and acoustics.
The system consists of modules that can work individually or in a group and is very robust. We also have an impedance tube for measuring the acoustic properties of materials.
