TY-8000A 100 kN Servo-Controlled Ring Stiffness Testing Machine

Overview

The TY-8000A 100 kN Servo-Controlled Ring Stiffness Testing Machine is an electromechanical universal testing system engineered for high-precision mechanical characterization of rigid and semi-rigid tubular structures—particularly large-diameter fiberglass-reinforced plastic (FRP) pipes, glass fiber reinforced polymer (GFRP) composites, and sand-embedded GRP pipes. It operates on the principle of controlled axial compression applied to a pipe segment mounted in a three-point bending configuration per ISO 9969 and GB/T 9647, enabling direct determination of ring stiffness (kN/m²) as defined by structural deformation under standardized loading conditions. Unlike conventional tensile testers, the TY-8000A integrates a high-rigidity frame, precision planetary gear reduction, and AC servo motor control to deliver stable low-speed compression profiles essential for creep-sensitive and time-dependent modulus evaluation. Its architecture supports both static and quasi-static mechanical testing across thermoset and thermoplastic matrices, with full compliance to ASTM D2412, ISO 1133, and EN 13476-2 methodologies when equipped with appropriate fixtures.

Key Features

• 100 kN load capacity with dual-range force transducer calibrated to ≤ ±0.5% accuracy over 0.4–100% full scale (FS)
• High-resolution displacement measurement (0.001 mm resolution) and closed-loop position control via滚珠 screw drive and servo feedback
• Programmable test modes including constant-rate loading, constant-displacement rate, force-controlled hold, displacement-controlled cycling, and low-frequency cyclic loading (0.001–5 Hz)
• Robust structural frame with 1200 mm maximum crosshead travel and 550 mm effective width, accommodating pipe diameters up to Ø1600 mm
• Integrated AC servo motor + planetary gearbox drive system ensuring torque stability, minimal backlash, and repeatability < 0.5% RSD across ≥100 identical tests
• Real-time multi-curve plotting: Load vs. Displacement, Load vs. Time, Stress vs. Strain, Displacement vs. Time, and Load vs. Extension (dual-extensometer mode)

Sample Compatibility & Compliance

The TY-8000A is validated for ring stiffness testing of thermoset and thermoplastic piping systems per GB/T 9647-2003, GB/T 21238-2007, and ISO 9969. With interchangeable fixtures—including ring compression platens, wedge-type grips, and hydraulic wedge clamps—it extends functionality to tensile strength (ISO 527-2), flexural modulus (ISO 178), tear resistance (ISO 34-1), and peel adhesion (ISO 8510-2). All test protocols are traceable to national metrology standards; force sensors are NIST-traceable and certified per ISO/IEC 17025. The system meets mechanical safety requirements of EN 61000-6-2 (EMC) and EN 61000-6-4, and its control software supports audit-ready GLP/GMP workflows with electronic signatures, user access levels, and FDA 21 CFR Part 11–compliant data integrity features.

Software & Data Management

The embedded Windows-based testing platform supports over 200 preloaded test methods—including ISO 34, ISO 37, ISO 178, ISO 527, ASTM D638, D790, D695, and EN 196-1—each configurable with custom pass/fail criteria, automatic yield point detection (tangent, offset, or secant method), and real-time statistical reporting (mean, SD, CV%, min/max). Raw data is stored in encrypted .tdms format with timestamped metadata (operator ID, environmental temp/humidity, calibration date, fixture ID). Export options include CSV, PDF reports with embedded graphs, and XML for LIMS integration. Audit trails record all parameter changes, test starts/stops, and data exports with immutable timestamps—fully compliant with ISO/IEC 17025 Clause 7.7 and EU Annex 11 requirements.
