YANRUN MC009-WAW-300G Microcomputer-Controlled Electro-Hydraulic Servo Universal Testing Machine

Overview

The YANRUN MC009-WAW-300G is a microcomputer-controlled electro-hydraulic servo universal testing machine engineered for high-precision mechanical property evaluation of metallic and non-metallic materials under static loading conditions. It operates on the principle of closed-loop hydraulic actuation, where a servo-controlled high-pressure oil system delivers precise force application through a bottom-mounted piston-cylinder assembly. The machine conforms to international standards for force measurement accuracy (ISO 7500-1 Class 1 or 0.5), and supports tensile, compression, bending, and shear testing per ASTM E4, ASTM E8/E21, ISO 6892-1, and GB/T 228.1. Its structural architecture—featuring a lower-positioned hydraulic cylinder, worm-gear-driven crosshead adjustment, and geometrically aligned load train—ensures exceptional coaxiality between upper and lower grips, minimizing parasitic bending moments and enhancing repeatability across long-term operation.

Key Features

• Bottom-mounted hydraulic actuator with precision gap-seal cylinder design for low friction, high durability, and minimal maintenance over extended service life.
• Independent transmission and positioning systems: Worm-gear mechanism adjusts test space without affecting load path geometry, ensuring consistent alignment and reduced measurement uncertainty.
• Four-channel closed-loop control system managing test force, specimen deformation, crosshead displacement, and test progression simultaneously with 24-bit A/D resolution (1/500,000 full scale, no range switching required).
• Dual-range load measurement capability covering 2–100% of full scale (FS), enabling accurate characterization of both low-force pre-yield behavior and high-load fracture events.
• Integrated hydraulic clamping system with automatic pressure regulation, supporting round specimens (Φ6–Φ26 mm) and flat specimens (up to 15 mm thick) with uniform grip stress distribution.
• Comprehensive safety architecture including overload protection (shuts down pump motor at >103% FS) and stroke limit detection (prevents mechanical overtravel at upper/lower extremes).
• User-configurable host color options and modular software interface compatible with Windows-based industrial PCs.

Sample Compatibility & Compliance

The MC009-WAW-300G accommodates standard and custom geometries per ISO 6892-1, ASTM E8, ASTM C39, and EN 12390-3. It supports tensile specimens up to 800 mm in gauge length and compression tests within a 700 mm working height. Bending configurations include three-point loading with adjustable span (450 mm standard), rollers of Φ30 mm diameter, and maximum deflection capacity of 150 mm. All force transducers are traceably calibrated to national metrological standards, and the system meets requirements for GLP-compliant environments when configured with audit-trail-enabled software. Documentation packages support FDA 21 CFR Part 11 readiness upon request, including electronic signature validation and change history logging.

Software & Data Management

Control and analysis are executed via YANRUN’s proprietary TESTMaster software, a real-time Windows application supporting multi-step test protocols, real-time curve overlay, and automated report generation in PDF, Excel, and XML formats. The software implements full data integrity safeguards: all raw acquisition channels (load, displacement, strain) are timestamped at ≥1 kHz sampling rate; all operator actions—including parameter edits, test starts/stops, and calibration interventions—are logged with user ID and time stamp. Exported datasets comply with ASTM E1434 and ISO 10360-5 for post-test statistical analysis and inter-laboratory comparison. Optional API integration enables connection to LIMS platforms via TCP/IP or OPC UA protocols.

Applications

• Mechanical qualification of structural steels, aluminum alloys, titanium grades, and high-strength composites in aerospace and automotive R&D labs.
• Quality assurance testing of welded joints, castings, and forged components per ASME BPVC Section IX and AWS D1.1.
• Concrete and masonry compressive strength verification aligned with ASTM C39 and EN 12390-3.
• Evaluation of polymer matrix composites and fiber-reinforced plastics under monotonic and cyclic loading profiles.
• Calibration reference use in metrology institutes and third-party certification bodies accredited to ISO/IEC 17025.
• Academic research involving constitutive modeling, fracture mechanics, and creep behavior under controlled displacement rates (0.01–50 mm/min).

FAQ

What standards does the MC009-WAW-300G comply with for force calibration and test execution?
It meets ISO 7500-1 (Class 1 or 0.5), ASTM E4 (verification of force-measuring instruments), ASTM E8/E21 (tensile testing of metals), and GB/T 228.1 (Chinese national standard equivalent to ISO 6892-1).
Can the system perform strain-controlled tests using extensometers?
Yes—the four-channel controller accepts analog inputs from clip-on or video extensometers, enabling true strain feedback for yield point determination and plastic strain measurement.
Is remote diagnostics and firmware update supported?
Standard Ethernet connectivity allows secure remote access via VPN for technical support, configuration review, and firmware upgrades under controlled change management procedures.
What is the recommended maintenance interval for the hydraulic power unit?
Oil filtration and system pressure verification are advised every 1,000 operating hours; full hydraulic oil replacement is recommended every 5,000 hours or biannually, whichever occurs first.
Does the machine support multi-specimen batch testing with automated reporting?
Yes—TESTMaster includes batch test sequencing, pass/fail logic based on user-defined limits, and consolidated reporting across up to 99 specimens per session.
