Overview
The Hengyi HY(DZPL)5000N Electromechanical Fatigue Testing Machine is a precision-engineered servo-controlled system designed for uniaxial tension-compression fatigue testing of metallic, polymeric, composite, and elastomeric specimens under controlled cyclic loading conditions. Utilizing a high-fidelity electromechanical actuation architecture—rather than hydraulic or pneumatic alternatives—this system delivers stable, low-noise force application with inherent energy efficiency, minimal maintenance requirements, and precise repeatability across extended test durations. The machine operates on the principle of sinusoidal or user-defined waveform-driven cyclic loading, enabling standardized evaluation of material endurance limits, crack initiation thresholds, and S–N (stress-life) behavior in accordance with internationally recognized fatigue testing protocols. Its ±5000 N dynamic load capacity and programmable frequency range up to 10 Hz make it especially suited for low-to-moderate frequency fatigue studies typical in R&D labs, quality control environments, and academic materials science departments.
Key Features
- Electromechanical servo-actuation system with brushless AC motor and precision ball-screw transmission—ensuring zero hydraulic fluid dependency, reduced thermal drift, and high positional fidelity.
- Integrated load cell with ±1% full-scale accuracy and real-time digital signal conditioning for robust force feedback control.
- Programmable waveform generation supporting sine, triangle, square, and custom user-defined profiles via embedded controller interface.
- Adjustable vertical test space (500 mm) accommodates diverse specimen geometries and fixture configurations—including threaded rods, dog-bone coupons, and miniature components.
- Modular clamping system with interchangeable grips (e.g., wedge-type, pneumatic, or hydraulic options available as accessories) optimized for brittle, ductile, or viscoelastic materials.
- Front-panel touchscreen interface with intuitive menu navigation, real-time curve plotting, and onboard data logging—enabling standalone operation without external PC dependency.
Sample Compatibility & Compliance
The HY(DZPL)5000N supports standard specimen types defined in ASTM E606 (strain-controlled fatigue), ASTM E466 (force-controlled axial fatigue), and ISO 1099 (metallic materials—axial fatigue testing). It is routinely deployed for evaluating small-diameter fasteners, thin-sheet alloys, biomedical implant wires, polymer sutures, and rubber isolators. All mechanical and electrical subsystems conform to GB/T 2611 (General Requirements for Testing Machines) and GB/T 3075 (Metallic Materials—Axial Fatigue Testing). When operated with validated software and calibrated transducers, test reports generated by this system satisfy GLP documentation requirements and support audit readiness for ISO/IEC 17025-accredited laboratories.
Software & Data Management
The system ships with Hengyi FatigueTest Pro v3.x—a Windows-based application supporting multi-channel acquisition (load, displacement, optional strain), real-time statistical monitoring (cycle count, peak/valley tracking, hysteresis loop analysis), and automated pass/fail logic per user-defined criteria. Data export is native to CSV, Excel (.xlsx), and universal .tdms formats. Audit-trail functionality records operator ID, parameter changes, calibration events, and test interruptions—aligning with FDA 21 CFR Part 11 principles for electronic records where enabled through optional validation packages. Remote monitoring and script-driven batch testing are supported via TCP/IP communication protocol.
Applications
- Determination of fatigue life and endurance limit in structural alloys (e.g., aluminum 6061-T6, Ti-6Al-4V) under constant-amplitude loading.
- Evaluation of hysteresis damping and modulus degradation in elastomers subjected to repeated compression cycles.
- Validation of solder joint reliability in microelectronics packaging assemblies using sub-500 N cyclic shear protocols.
- Biomechanical assessment of orthopedic wire fatigue resistance per ASTM F1800 and ISO 5832-1 standards.
- Quality assurance testing of automotive NVH components—including engine mounts and suspension bushings—under road-spectrum-simulated waveforms.
FAQ
What is the maximum achievable test frequency at full ±5000 N load?
At rated dynamic capacity, the system maintains stable operation up to 10 Hz; however, sustained testing above 5 Hz is recommended only with active cooling and verified specimen resonance suppression.
Can the machine perform strain-controlled fatigue tests?
Yes—when equipped with an extensometer (e.g., clip-on or non-contact video extensometer), closed-loop strain control is fully supported via FatigueTest Pro software.
Is third-party calibration certification available?
Hengyi provides NIST-traceable calibration certificates upon request, compliant with ISO/IEC 17025 requirements when performed by accredited partners.
Does the system meet electromagnetic compatibility (EMC) standards for laboratory integration?
The unit complies with EN 61326-1:2013 for EMC emissions and immunity in industrial laboratory environments.
What is the warranty coverage and service response time?
Standard warranty covers parts and labor for 24 months; extended service plans include remote diagnostics, annual performance verification, and priority on-site technician dispatch within 72 business hours.
