 Servohydraulic Testing Machines 00 Series

 

Axial dynamic servo hydraulic testing machines series H. 5 series 00 in vertical design up to 500kN with servo cylinder in the foundation are designed to perform low and high cycle fatigue tests, fracture toughness, crack propagation, etc. This series of machines is characterized by high frame rigidity and mechanical resistance. The range of a given machine depends on the dynamic stroke and frequency. A specific test set is derived from these parameters, which consists of a test frame, a servo-hydraulic cylinder and a hydraulic unit..

 
 
KEY FEATURES OF THE H.5 SERIES WITH A CYLINDER IN THE BASIC FUNDATION

  • Stand design with high axial and torsion rigidity and mechanical resistance.

  • Possibility of extending the test frame by automatic electro-hydraulic transfer and clamping of the crossbar.

  • Guaranteed system coaxiality in accordance with ASTM E 1012.

  • Integrated servo cylinder in center crossbar of the machine.

  • Torsion induced hydraulically or electromechanically depending on frequency and number of cycles.

  • Test control by proportional or servo valve with the possibility of control in the power and position loop.

  • Complete test evaluation and control is provided by Test & Motion material testing software – DYNPACK.

  • Combined torsion load cells located on the piston rod operating in the accuracy class according to EN ISO 7500-1, ASTM E4 with the possibility of linearization.

  • Powerful compact hydraulic units of the HAD series with low noise level thanks to the PAC system.

  • HALT 18 hydraulic unit diagnostics controlled by TOUCH LCD SIEMENS as standard.

  • The H.8 series machines comply with all the above-mentioned EC directives on machinery and equipment and work in accordance with the new safety functions according to EN ISO 13850-SIL 1/PL.

  • The machine is controlled by measuring and control electronics of the EDCi series with a sampling frequency of 10 kHz. Analog signal resolution level ± 250,000 divisions (20 ms).

  • Integration of special grips for axial torsion tests or various jigs according to standards, etc.

  • High-precision tests with temperature chamber or high-temperature furnace.
