MIKAT–U system is designed for high-cycle fatigue (HCF) testing of aircraft engine blades both in fundamental and high-frequency vibration modes. It is also used in research laboratories to study fatigue limits of new alloys and weld techniques.

MIKAT–U is a complete desktop solution incorporating piezoelectric exciter, power amplifier and non-contact vibration-feedback transducer for automated testing under software control. For high-temperature applications the system can be optionally equipped with high-temperature SiC heater (maximum test specimen temperature 1000°C) and temperature control unit.

The system is easy to use and to maintain. Due to resonant operation it requires minimal power for typical tasks.

Key specifications:

Operating frequency     300 – 20000 Hz
Output power of the amplifier     200 – 500 W
Total weight    25 – 50 Kg
Occupied area    1 m²
Power supply    220V / 50 Hz

UZS-R system is designed for high-cycle fatigue (HCF) testing of dovetail joints of aircraft gas-turbine engine blades. The system can reproduce real life operating conditions of the joints, which are subjected to superimposition of high-temperature, static load and dynamic excitation. This allows to accurately determine realistic fatigue limit.

Modular concept allows testing specimens from disks, gears and other parts.

The system incorporates tensioning device with electric motor drive and gauge, connecting rods, custom-tailored fixtures and heaters for specimens of different size and shape, temperature control unit and non-contact vibration-feedback transducer for automated testing under software control. The dynamic load is generated by electromagnetic exciter. The system can be adapted for mounting on customer’s vibrostand.

No supporting equipment (hydraulics, cooling, etc.) is required.

Key specifications:

Operating frequency     150 – 350 Hz
Maximum static load     15,000 kgf
Maximum heating temperature    750 ºC
Heater power consumption    2 kW
Total weight    350 kg
Occupied area    2 m2
Power supply    220 V/50 Hz

The A-series power amplifiers are designed to drive directly high-power electrodynamic or piezoelectric vibrostands. They employ digital switching schematics (D-class), are characterized by high efficiency (up to 83%) and stability over time and environmental conditions.

The amplifiers are oriented to typical tasks in fatigue and vibration testing therefore they are rated for long continuous operation at maximum output power with monotonous (sinusoidal) signals.

Key specifications:

Maximum output power (continuous)    500/1000/2000 W
Operating frequency     20 – 5000 (15000) Hz
Minimum input impedance    10 kOhm
Input range    1 VAC
Power supply    220 V/50 Hz
