Double-column electro-hydraulic servo test system for performance and durability tests of shock absorbers and dampers.
Overview
This is a vertical double-column electro-hydraulic servo damper test system designed per GB/T 18777-2019 "Performance Requirements and Bench Test Methods for Shock Absorbers of Automobile Suspension Systems" and QC/T 545 "Bench Test Methods for Automotive Telescopic Shock Absorbers". It is used for indicator (P-V) tests, damping-characteristic tests, velocity and temperature tests, dynamic-stiffness tests and fatigue/durability tests of hydraulic/gas dampers in automotive, rail transit, construction machinery and seismic isolation applications. The main frame is a top-cylinder double-column structure driven by a hydraulic servo actuator; a PC and servo controller provide closed-loop displacement/force/strain control, acquire force-displacement and force-velocity data in real time, plot indicator and damping curves, and automatically calculate damping coefficient, dynamic stiffness and other indices.
Applications
• Road and highway engineering laboratory testing
• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
Features
• Robust construction suitable for both laboratory and field use
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the Electro-Hydraulic Servo Damper Testing System comply with?
A1: The Electro-Hydraulic Servo Damper Testing System is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the Electro-Hydraulic Servo Damper Testing System be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
