H.8 – axial torsional servohydraulic testing machines
Servohydraulic vertical dynamic axial torsion testing machines of the H.8 series are used to perform torsional oscillating or tensile / torsional tests of test samples or whole products in the engineering, pharmaceutical, construction and automotive industries, including academic institutions. These machines have an axial / torsional test drive mounted on the upper cross member. The optional base plate with T-slots in the crossbar makes these machines very versatile.

Basic modifications of axial torsion machines!
Standard set of axial / torsional testing machine
Focus on these 3 basic machine parts …
The right choice of axial / torsional hydraulic servo cylinder
Combined servo cylinder
If you choose from the table the appropriate combination of machines of the H.8 series, ie. axial force and torsional moment, then it is necessary to define the following parameters:
What will be the magnitude of the amplitude? What max frequency will I use?
What will be the maximum angle of rotation + -? What max frequency will I use?
Based on these input parameters, the entire test set of the machine can be precisely specified, including dimensional size, power input, etc.
A suitable hydraulic unit to meet your requirements and location
Appropriate choice of Hydraulic unit (HU)
Based on the correct specification of the combined test servo cylinder, a suitable compact hydraulic pressure unit designed for fatigue tests is defined. HU is always equipped with the HALT 18 – Diagnostic SIEMENS control system with system monitoring of conditions, pressures and service intervals via a touch LCD.
Cooling of Hydraulic unit .
How will I cool the hydraulic power unit? Air or water cooling? Find out your options.
Do I need to deal with noise?
The possibility of covering HU is made by a special anti-noise cover PAC <72 dB. Easy access from all sides using quick couplings allows easy handling around the HU (filter change, oil change, etc.). Thanks to the silent block suspension, the HU can be placed directly on the test room floor.
Appropriate selection of control unit and test software, including modules
Measuring and control electronics
EDCi Control electronics with real-time synchronization of all measuring and control channels must be supplied for each test axis. Choose the RMCi7 or RMCi8 series remote control with OLED display integrated CENTRAL STOP.
Basic parameters of electronics
Analog signal resolution level ± 250,000 divisions (20 ms). Internal frequency 64 bit, data acquisition 32 bit, AD 24 bit, arithmetic, sampling frequency 10kHz. Integrated RS232 for VIDEO extensometers. PC connection – Ethernet 10/100 Mbit, USB 2.0.
