Overview
The Hengyi HY-0580LKUI is a single-column electromechanical universal testing machine engineered for high-reproducibility mechanical characterization of advanced laminated and composite materials—specifically optimized for three-point bending strength evaluation of aluminum-titanium (Al-Ti) clad plates. It operates on the principle of controlled displacement actuation via a precision ball-screw-driven crosshead, with force feedback acquired through calibrated S-type or cantilever load cells. The system conforms to static uniaxial testing fundamentals defined in ISO 7500-1, ASTM E4, and GB/T 16491-2008, delivering traceable, standards-compliant data for R&D, quality assurance, and regulatory submission workflows. Its rigid monolithic frame, low-inertia drive architecture, and real-time closed-loop control ensure minimal compliance error and consistent load train alignment—critical for brittle or anisotropic composites where localized stress concentrations govern failure mode.
Key Features
- Modular load cell configuration supporting 1 N to 5000 N capacities, enabling seamless transition between micro-scale interfacial shear testing and macro-scale structural bending evaluation.
- Full-scale force resolution of ±500,000 digital counts without range switching—maintaining constant resolution across the entire measurement span per ISO 376 Annex C requirements.
- Adjustable crosshead speed from 0.001 mm/min (for creep or relaxation studies) to 500 mm/min (for high-rate quasi-static loading), with velocity accuracy maintained within ±0.5% of setpoint per ASTM E2309.
- Dual-mode motion control: manual jog operation for precise specimen alignment and automated programmable sequences for standardized test protocols (e.g., ISO 14125 for flexural properties of fiber-reinforced plastics).
- Integrated electronic limit switches and hardware-based overload cutoff (110% FS threshold) prevent mechanical damage during unexpected specimen rupture or fixture misalignment.
- Self-diagnostic subsystem continuously monitors drive current, encoder feedback, and amplifier voltage—triggering immediate shutdown upon detection of overpressure, overcurrent, or position deviation exceeding 0.1 mm.
Sample Compatibility & Compliance
The HY-0580LKUI accommodates flat-sheet specimens up to 120 mm wide and 800 mm tall, making it suitable for standardized three-point bending configurations per ASTM D790, ISO 178, and GB/T 3354. Its open-front design allows rapid fixture exchange—including custom-designed three-point bend supports with radiused rollers (R ≥ 5 mm) and hardened steel anvils meeting ISO 2041 specifications. The machine satisfies metrological requirements of GB/T 2611-2007 (General Technical Requirements for Testing Machines), GB/T 16852.1-2008 (Verification of Static Uniaxial Testing Machines), and ISO 7500-1:2018 (Calibration of Force-Proving Instruments). All force and displacement outputs are traceable to national standards via factory calibration certificates compliant with ISO/IEC 17025 procedures.
Software & Data Management
Control and analysis are executed via Hengyi’s proprietary PC-based software suite, supporting Windows 10/11 environments and compliant with FDA 21 CFR Part 11 for audit-trail-enabled data integrity. The interface enables creation of multi-step test profiles (e.g., preload → ramp → hold → unload), automatic calculation of flexural modulus, yield strength, and fracture toughness (KIC-equivalent for thin plates), and export of raw time-stamped data in CSV or XML formats. Software modules include GLP-compliant user access levels, electronic signature capability, and configurable report templates aligned with ISO/IEC 17025 documentation requirements. Raw sensor data is stored locally with SHA-256 hash verification to prevent post-acquisition tampering.
Applications
- Three-point bending strength and stiffness quantification of Al-Ti bimetallic plates used in aerospace heat exchangers and marine propulsion components.
- Mechanical screening of diffusion-bonded interfaces under controlled strain rates to assess interlayer adhesion integrity.
- Quality conformance testing per GB/T 3923 (woven fabric tensile), GB/T 1040 (plastics tensile), and ISO 527 series for polymer matrix composites.
- Development validation of novel clad architectures—e.g., Ti-6Al-4V/AA2024 stacks—where asymmetric yield behavior necessitates precise moment-arm calibration.
- Educational use in university materials science labs for hands-on instruction in ASTM E8/E8M principles and fracture mechanics fundamentals.
