Overview
The Hengyi HY-0580UINGYU Electromagnetic High-Frequency Dynamic Tension-Compression Fatigue Testing Machine is a precision-engineered, microprocessor-controlled electromechanical fatigue system designed for high-reproducibility dynamic mechanical characterization of small-scale specimens under cyclic loading. Unlike hydraulic or servo-hydraulic systems, this instrument employs a direct-drive linear electromagnetic actuator—eliminating oil contamination, reducing maintenance, and ensuring clean, quiet operation ideal for laboratory environments including biocompatibility labs, polymer research centers, and academic materials science facilities. Its core measurement principle relies on closed-loop digital servo control of axial force and displacement, synchronized with high-speed data acquisition (up to 10,000 Hz), enabling accurate quantification of fatigue life, hysteresis behavior, stiffness degradation, and energy dissipation across a broad frequency spectrum (0.01–200 Hz). The system complies with fundamental metrological requirements defined in GB/T 2611–2007 and JB 9397–2002, and its mechanical architecture supports full traceability to international standards including ISO 1099, ASTM E466, ASTM E606, and ISO 12106 for axial fatigue testing.
Key Features
- Electromagnetic linear actuation with zero lubricant requirement—ensures long-term dimensional stability, eliminates fluid leakage risks, and meets ISO 14001 environmental compliance criteria.
- Dual-column rigid frame with T-slot test table and precision-ground guide rails—optimized for alignment accuracy and minimal parasitic bending moments during high-frequency cycling.
- Full-range load cell (5000 N capacity, 0.5-class accuracy) with 30,000-count resolution—no internal range switching, maintaining constant resolution from 0.1% to 100% of full scale.
- Integrated safety architecture: electronic travel limits, overload protection at 110% of rated load, real-time self-diagnostic routines for drive electronics, sensor integrity, and power supply anomalies.
- Multi-mode motion control: programmable ramp, hold, step, and cyclic profiles; user-definable waveforms including sine, triangle, square, trapezoidal, and arbitrary waveform import via CSV.
- Motorized crosshead positioning with dual-speed (fast/slow) jog control and automatic return-to-start functionality—reducing setup time between sequential tests.
Sample Compatibility & Compliance
The HY-0580UINGYU accommodates a wide range of specimen geometries and material classes, including polymeric films (e.g., PET, PE), elastomeric biomaterials (hydrogels, silicone rubber), textile fibers, thin metallic foils (Ti-6Al-4V, stainless steel 316L), nanocomposite laminates, adhesive bonds, and orthopedic implant coatings. Its 380 mm test width and 800 mm vertical stroke support standardized dumbbell, dog-bone, and custom geometry specimens per ISO 527-2, ASTM D638, ISO 37, and ASTM D412. All force, displacement, and strain measurements are calibrated against national metrological standards (CNAS-accredited traceability) and validated per ISO/IEC 17025 requirements. The system supports audit-ready documentation for GLP and GMP-regulated environments—including configurable electronic signatures, 21 CFR Part 11-compliant user access logs, and immutable test record archiving.
Software & Data Management
Control and analysis are executed via Hengyi’s proprietary TestMaster™ software suite (Windows 10/11 compatible), featuring real-time graphical display of force-displacement loops, stress-strain hysteresis curves, cycle-by-cycle parameter tracking (peak load, min load, stiffness, energy loss), and automated S–N curve generation. Data export options include CSV, Excel (.xlsx), PDF reports with embedded metadata (operator ID, calibration date, environmental conditions), and XML for LIMS integration. The software supports script-based batch testing, conditional termination logic (e.g., stop on 5% stiffness drop or 10⁶ cycles), and post-test Fourier transform analysis for harmonic distortion assessment. All raw acquisition data are stored in binary format with timestamped headers, ensuring forensic-level reproducibility for regulatory submissions.
Applications
- High-cycle fatigue evaluation of biomedical polymers under physiological loading frequencies (0.5–5 Hz).
- Dynamic mechanical analysis (DMA) of thermoplastic elastomers across temperature-controlled chambers (when integrated).
- Adhesion fatigue testing of pressure-sensitive tapes and medical transdermal patches per ASTM D3330.
- Cyclic tensile durability of wearable textile sensors and conductive elastomer composites.
- Creep-recovery and stress relaxation profiling of soft tissue simulants (e.g., agarose, alginate hydrogels).
- Validation of finite element models using experimentally derived hysteresis and phase lag data.
FAQ
What is the maximum achievable test frequency in closed-loop force control mode?
The system maintains stable closed-loop control up to 50 Hz at full 5000 N amplitude; above 50 Hz, displacement-controlled sinusoidal excitation remains stable to 200 Hz with reduced load fidelity.
Does the system support high-temperature or sub-ambient environmental chambers?
Yes—standard mounting interfaces accommodate commercially available thermal chambers (–70 °C to +300 °C) with feedthrough-compatible load cell and extensometer cabling.
Can third-party sensors (e.g., video extensometers, acoustic emission transducers) be synchronized with the test controller?
Yes—TTL trigger outputs and analog voltage inputs enable hardware-level synchronization with external instrumentation at ≤10 kHz sampling rates.
Is firmware update capability available remotely?
Firmware updates are performed via secure USB transfer only; no remote network connectivity is implemented to preserve system integrity and meet ISO/IEC 27001-aligned cybersecurity protocols.
What documentation is provided for regulatory audits?
Each unit ships with Factory Calibration Certificate (traceable to NIM, China), Installation Qualification (IQ), Operational Qualification (OQ), and a complete Software Validation Package compliant with ICH Q9 and ISO 13485 Annex A requirements.
