Description
High-Capacity Hydraulic Fatigue Testing Machine
These machines play a vital role in industries that demand rigorous durability testing. For instance, they are widely used in
| Feature | Description |
|---|---|
| Purpose | Conduct high-cycle fatigue (HCF), low-cycle fatigue (LCF), fracture mechanics, crack propagation, and combined static/dynamic tests. As a result, they accurately evaluate material/component durability under repeated loading and predict service life effectively. |
| Applications | Aerospace, automotive, civil engineering (bridges/concrete), railways, shipbuilding, military, biomedical implants, and advanced materials R&D. In addition, they support a wide range of research needs. |
| Capabilities | Force capacities from 100 kN to 5000 kN+; supports sinusoidal, triangular, and random waveforms. Furthermore, frequencies reach several hundred Hz, while integrating static and dynamic loading seamlessly. |
| Sensors | Fatigue-rated load cells provide accurate force measurement. Meanwhile, high-resolution displacement sensors (e.g., LVDT or extensometers) enable real-time strain monitoring. |
| Test Range | Accommodates large-scale specimens and components; actuator strokes up to 150-300 mm. Additionally, versatile fixtures allow axial, bending, torsion, and multi-axial testing. |
| Automation & Control | Servo-hydraulic control includes waveform generation, cycle counting, adaptive control, and multi-channel data acquisition. Therefore, it ensures full compliance with standards like ASTM E466 and ISO 1099. |
| Real-Time Analysis | Generates force-displacement loops, stress-strain hysteresis, S-N curves (Wöhler curves), and crack growth plots. Thus, it offers comprehensive fatigue evaluation in real time. |
| Safety & Compliance | Includes overload protection, emergency stops, hydraulic buffering, and specimen protection features. Overall, this guarantees full traceability to international standards (e.g., ASTM, ISO). |
