Technical principle and system composition of universal material testing machine

loading system
Drive mode: The ball screw is driven by a servo motor to achieve stepless speed regulation (0.05-500mm/min) and precise displacement control.
Load capacity: covering 1kN to 3000kN, meeting testing requirements from small specimens to large components.
Oil cylinder design: divided into upward type (space saving) and downward type (high stability), suitable for different testing scenarios.
measurement system
Sensor accuracy: Imported high-precision sensors (such as 0.1 level) ensure a force measurement error of ≤± 0.5%.
Deformation measurement: equipped with extensometers or laser rangefinders to achieve micro strain level (10 ⁻⁶) deformation detection.
Displacement resolution: up to 0.01 μ m, meeting the requirements of high-precision material analysis.
control system
Closed loop control: PID algorithm is used to adjust the loading speed and force value in real time to ensure testing stability.
Software features: Supports multilingual interface, dynamic display of test curves, and automatic calculation of mechanical parameters (such as yield point and fracture energy).
Safety protection: equipped with limit protection, overload protection, and automatic shutdown function for sample fracture, ensuring operational safety.
Data collection and analysis
Sampling rate: up to 1000Hz, capturing transient mechanical behavior.
Standard compatibility: Complies with international standards such as GB/T 228, ASTM E4, ISO 7500-1, and supports automatic generation of test reports.
