WANCE HUT-DP Series Electro-Hydraulic Servo Universal Testing Machine

Overview

The WANCE HUT-DP Series Electro-Hydraulic Servo Universal Testing Machine is a high-capacity, precision-engineered mechanical testing system designed for static and quasi-static mechanical characterization of structural materials under tension, compression, bending, and shear loading conditions. Built upon a robust four-column load frame architecture with dual-acting servo-controlled hydraulic actuation, the system delivers stable, high-fidelity force application across its full rated capacity range—from 600 kN to 2000 kN. Its electro-hydraulic servo control architecture enables closed-loop regulation of load, displacement, and strain at sub-millisecond response times, ensuring compliance with stringent dynamic fidelity requirements in standardized mechanical testing protocols. The machine operates within an ambient temperature range of –40 °C to +1000 °C when integrated with certified environmental chambers or high-temperature furnaces—enabling conformance to ASTM E21, ISO 6892-2, GB/T 228.2, and GB/T 228.3 for elevated- and low-temperature tensile evaluation.

Key Features

• Four-column rigid frame construction with optimized column spacing (550×370 mm to 770×470 mm) for enhanced lateral stability and minimal deflection during high-load compression tests.
• High-resolution force measurement system calibrated to 0.5 accuracy class per ISO 7500-1 and JJG 1063-2010, delivering ±0.5% relative error over the full 1–100% FS range without range switching.
• Ultra-fine deformation resolution of ±1/600,000 FS, supporting precise strain-controlled testing and low-strain modulus determination in accordance with ASTM E83 and ISO 5893.
• Programmable piston motion profiles: upward speed up to 230 mm/min; downward speed up to 550 mm/min; enabling rapid specimen setup and efficient cycle times in production QA environments.
• Modular gripping system accommodating round specimens from φ10 mm to φ100 mm and flat specimens up to 80 mm thick—compatible with standard wedge-action, pneumatic, and hydraulic grips.
• Integrated oil source with pressure-regulated servo valve manifold, redundant filtration, and temperature-stabilized hydraulic fluid conditioning to ensure long-term repeatability and reduced maintenance intervals.

Sample Compatibility & Compliance

The HUT-DP series supports mechanical testing of metallic alloys, reinforced concrete, pre-stressed steel strands, welded wire mesh, structural ceramics, polymer composites, and masonry units. It is fully compatible with industry-standard accessories including high-temperature furnaces (up to 1200 °C), environmental chambers (–70 °C to +150 °C), automatic extensometers (contact and non-contact), video-based digital image correlation (DIC) systems, and load-cell-integrated shear fixtures. The system meets or exceeds the metrological and functional requirements of GB/T 16826-2023, GB/T 2611-2022, ASTM E4, ASTM E8/E9/E21, ISO 7438, ISO 6892-1/2, and EN 10002-1. All calibration certificates are traceable to NIM (National Institute of Metrology, China) and support GLP/GMP audit readiness per ISO/IEC 17025:2017.

Software & Data Management

The system operates under WANCE TestMaster™ v5.2—a Windows-based, multi-threaded control and analysis platform compliant with FDA 21 CFR Part 11 for electronic records and signatures. Software modules include real-time PID tuning, test method templates aligned with GB/T 228.1, ASTM E8, and ISO 6892-1, automated report generation (PDF/Excel), raw data export (ASCII/CSV), and built-in uncertainty calculation per GUM (JCGM 100:2008). Audit trails record all operator actions, parameter changes, and calibration events with time stamps and user IDs. Data encryption, role-based access control, and optional network integration support centralized lab management in multi-station facilities.
