Servohydraulic testing machines are used for materials and component testing under pulsating or alternating loads, with periodic or random signals. Quasi-static and dynamic loads are also easily achieved.
The strength of servohydraulic testing machines is found in the wide range of applications for which they are suitable. In terms of force, amplitude and frequency, they can be used universally. This also allows servohydraulic testing machines to be used for multi-axis fatigue tests or to perform crash tests at speeds of up to 20 m/s. Their modular design includes testing systems up to 2500 kN, and even higher with customized versions.
With characteristics such as high stiffness, ZwickRoell servohydraulic testing machine load frames have been specially designed to sustain the tough demands of fatigue tests. Servohydraulic testing machines can also be used for effortless performance of fracture mechanics tests.
Depending on the test requirements and ergonomic demands in day-to-day operations, the testing actuator can either be mounted below (HA series) or above (HB and HC series) the test area.
The high-speed testing machines are ideal for puncture tests or high-speed tensile tests. The HTM series high-speed testing machines are ideally suited for the determination of material behavior under crash loading.
For the determination of high cycle fatigue strength, ZwickRoell can provide a customized modular system to cover all testing requirements, comprising actuators, hydraulic power packs, distribution units, dynamic testing machines and other accessories. High-performance measurement and control electronics are available with testControl II , while ZwickRoell's testXpert II testing software provides support during test set-up and performance of dynamic tests for the determination of durability. Customized fatigue testing solutions are always available in addition to standardized products.
