The perfect testing machine for fatigue tests on components
Standard versions of the HB load frame in the 50 to 2,500 kN range have the testing actuator located above the test area. The version with integrated T-slotted platform allows flexure tests and component testing to be performed in addition to standard high cycle fatigue tests.
The test frame features extremely high stiffness, resulting in natural resonance. To avoid unwanted flexural stresses in the specimen the load frames are accurately aligned.
The final element in our dynamic testing product portfolio is the manufacture of all the necessary accessories such as hydraulic power packs, servohydraulic testing actuators, or hydraulic distribution units. Our portfolio is constantly being expanded through a program of continuous development and inclusion of new products, allowing us to satisfy our customer’s most demanding quality requirements while continually improving the quality of our products.
Fatigue test on welded steel specimens
Many welded components are subjected to cyclic loads, which is why these welded connections are tested using a dynamic fatigue test. Typically, these specimens cannot be clamped centrally in the specimen grips. The hydraulic grips shown here are ideal for this application, as the offset can be adjusted with the grips.

Common fatigue tests
Materials and components may fail prematurely under oscillating loads. For this reason, the behavior of materials under alternating mechanical loading is an important decision criterion, for which the necessary data are obtained through testing.
There are two categories of fatigue in materials testing:
