Electromechanical linear dynamic testing machines of EP series based on linear motor technology are designed for testing a wide range of materials and components in dynamic and static modes where oil-free and noiseless drive technology is preferred in the plastics, aerospace or medical industries with a maximum test frequency of 200Hz. All modifications we make to dynamic and fatigue test systems are designed so that the customer can fully rely on its function in high cycles, low cycle fatigue tests, crack propagation and growth, and other types of tests.
KEY FEATURES OF EP SERIES
- Robust vertical stand design with extremely high lateral rigidity, resonant and mechanical resistance in dynamic mode for each test axis of the machine.
- Powerful compact hydraulic units of the HAD series with low noise level designed for fatigue tests with water cooling Diagnostics of the hydraulic unit HALT 18 controlled by TOUCH LCD SIEMENS at standard.
- Control of individual axes by proportional or servo valve in power and position loop. Complete test evaluation and control is provided by Test & Motion material testing software – DYNPACK.
- The EP 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. 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.
- The compact measuring and control electronics of the EDCi Control – BIAXIAL series are preferably designed to handle this top application. Synchronization of all measuring and control channels with sampling frequency 10kHz in real time...
- Analog signal resolution level ± 250,000 divisions (20 ms).
- Integrated BENTROD measuring and setting unit for each axis designed for evaluation and optimization of concentric and edge alignment correction according to ASTM E1012 Dynamic hydraulic grips with wedge pressure designed for clamping cross flat specimens with centering.
- Unique advanced axial, transverse and biaxial video extensometer EOX using the latest digital image correlation technology thanks to the telecentric lens High-precision tests with temperature chamber or high-temperature furnace.
