Test Principle
Hydraulic oil is pumped from the reservoir through a servo valve into the working cylinder. The computer modulates oil flow via the servo valve, enabling precise control of loading speed and test modes (e.g., constant force/displacement). Strain is measured via displacement sensors or an extensometer.
