Servo-Hydraulic Testing Machines
The Zwick servo-hydraulic testing machines are flexible and reliable testing systems. They can be adapted to multiple applications such as tests on standard specimens or individual components and assemblies (rubber-metal elements or artificial hips). All servo-hydraulic testing machines are optimized to meet your requirements.
The different load frame types have been designed to guarantee a long life and easy maintenance so that they are a reliable long term investment. Their capacity ranges from 5 kN up to 1000 kN and their testing frequency from a few Hz up to 100 Hz or 200 Hz thanks to their enhanced stiffness and increased natural frequency.
The HA load frames are characterized by actuator mounted in the lower crosshead. They have an enhanced axial and lateral frame stiffness and side load capability.
Even complex components can be easily mounted and tested thanks to the actuator mounted in the upper crosshead of the HB load frames and the possibility of installing a T-slotted plate (option).
The HC load frames are designed to be installed on a mounting table. In the standard version, they are equipped with a hard-chrome-plated T-slotted table, which allows an optimized use of the load frames in the biomedical sciences area or with corrosives materials such as saline baths.
Zwick proposes, depending on your needs, linear, torsion as well as combined linear/torsion actuators, available with various strokes and system pressures. Our technical consultants help you define the servo-valve types needed.
The Zwick polymer bearing actuators are designed for applications with low side loads and flexure moment. They guarantee our customers an advantageous cost-performance ratio.
The hydrostatic bearing actuators are optimized for tests that requires high frequencies and high piston speed, as well as for applications with higher side loads and flexure moment. | |
Zwick dynamic grips guarantee a simple and safe clamping of the specimen as well as a backlash-free through zero loading.
The alternating load grips have been designed for testing threaded- and shoulder-head specimens under tensile, compressive or alternating load. The low weight of the grips minimizes the acceleration effects.
The mechanical grips are designed for static and dynamic testing of flat and round specimens under tensile, compressive and alternating load. Their simple design is a guarantee for a long life and ease of use.
The hydraulic wedge grips have been designed for testing materials under tensile, compressive or alternating load also combined with torsion load. Their design is also optimized for use with optical extensometers.
The hydraulic grips are designed for testing flat and round specimens under tensile, compressive or alternating load and are particularly adapted for fatigue testing. Their design has been optimized so that other testing tools can be used without removing them.
As Zwick is keen to deliver ready to use testing systems, we also propose hydraulic power packs with a system pressure of 210 bar or 280 bar, appropriate controllers of the HydroWin 96xx series and dynamic software.
