Overview
The Hengyi HY-100N·m Microcomputer-Controlled Electronic Torsion Testing Machine is an electromechanical system engineered for high-precision static and quasi-static torsional characterization of adhesives, metallic and non-metallic materials, biomedical implants (e.g., bone screws, dental abutments), and structural components. It operates on the principle of controlled angular displacement under applied torque, enabling direct measurement of torsional stiffness, yield torque, ultimate torsional strength, plastic deformation angle, and energy absorption capacity. The system complies with internationally referenced mechanical testing standards—including JB/T 9370–1999 (Technical Specifications for Torsion Testing Machines) and GB/T 10128–2007 (Metallic Materials—Room Temperature Torsion Testing Method)—and supports user-defined test protocols aligned with ASTM E143, ISO 7886-2, or custom regulatory specifications for orthopedic or adhesive qualification.
Key Features
- High-fidelity torque sensing with ±0.5% full-scale accuracy and 0.001 N·m resolution, achieved via calibrated strain-gauge-based torque transducer integrated into the drive shaft.
- Dual-mode control architecture: real-time torque-controlled and angle-controlled loading profiles, with automatic transition between modes during progressive failure testing.
- Precision rotary encoder with 0.0045° angular resolution and ±0.5% speed accuracy across 0–1000°/min range, supporting both slow-rate creep evaluation and rapid torsional fatigue pre-conditioning.
- Bidirectional actuation capability with programmable reversal logic, essential for hysteresis loop analysis and cyclic torsion endurance assessment.
- Modular gripping system accommodating specimens from Φ1 mm to Φ5 mm diameter; optional custom jaw sets available for flat, threaded, or irregular cross-sections.
- Statically rigid frame (200 kg mass, cast-iron base) minimizes parasitic deflection, ensuring measurement integrity during high-torque transients up to 100 N·m.
- Integrated electronic controller with isolated analog signal conditioning, eliminating ground-loop interference and supporting long-term stability in laboratory environments.
Sample Compatibility & Compliance
The HY-100N·m platform accommodates a broad spectrum of specimen geometries and material classes: single-lap adhesive joints (e.g., epoxy, cyanoacrylate, silicone RTV), metallic wires and rods (stainless steel, titanium alloys), polymer tubing (PEEK, UHMWPE), and orthopedic fixation devices (cortical screws, intramedullary nails). All hardware and firmware conform to electromagnetic compatibility (EMC) Class B requirements per IEC 61326-1. Test data acquisition meets GLP and GMP documentation prerequisites, with timestamped raw values stored in CSV and XML formats traceable to NIST-traceable calibration certificates. Optional audit trail module enables 21 CFR Part 11–compliant electronic signatures and change history logging.
Software & Data Management
The proprietary Hengyi TorsionTest Suite (v4.2+) runs on Windows OS and provides synchronized dual-channel acquisition at 1 kHz sampling rate. Real-time visualization includes dynamic overlays of torque–twist angle, torque–time, and twist rate–torque curves. Automated report generation outputs PDF and printable formats compliant with GB/T 228.1 and ASTM E8/E8M annexes, embedding test parameters, statistical summaries (mean, SD, CV%), pass/fail flags against threshold criteria, and digital signatures. Data export supports third-party analysis tools (MATLAB, Python pandas, Minitab) via structured JSON or HDF5 containers. Calibration management utilities enforce periodic verification intervals and store historical drift compensation coefficients.
Applications
- Quantification of adhesive bond integrity in aerospace composite assemblies under torsional shear stress.
- Evaluation of torsional fatigue life in medical device anchoring systems per ISO 14801.
- Validation of thread-forming screw performance in synthetic bone analogs (e.g., polyurethane foam blocks).
- Characterization of viscoelastic recovery behavior in thermoplastic elastomer couplings.
- Quality control screening of batch-to-batch consistency in structural epoxy formulations.
- Research-grade investigation of torsional fracture mechanics in brittle ceramics and fiber-reinforced laminates.
FAQ
What standards does the HY-100N·m machine support out-of-the-box?
It natively implements JB/T 9370–1999, GB/T 10128–2007, and JJG 269–2006. Custom test methods can be loaded via script-based protocol editor.
Can the system perform cyclic torsion tests?
Yes—programmable sine, triangle, or trapezoidal waveforms with variable amplitude, frequency, and mean torque offset are supported.
Is remote operation possible?
The system supports TCP/IP-based network control and monitoring through secure SSH tunneling; no cloud dependency or vendor-hosted infrastructure is required.
How is calibration traceability maintained?
Each unit ships with a factory calibration certificate traceable to CNAS-accredited metrology labs; onboard self-calibration routines verify zero drift and gain stability prior to each test sequence.
What safety mechanisms prevent over-torque damage?
Hardware-enforced torque limiters, emergency stop circuitry meeting EN ISO 13850, and software-configurable soft limits operate independently to halt motion within 20 ms of threshold breach.
