Theory & Method

A Universal Testing Machine (UTM) evaluates the mechanical behavior of materials by applying a controlled force to a specimen while measuring the resulting load, deformation, and displacement. Depending on the test method, the specimen may be subjected to tension, compression, bending, shear, peel, or other mechanical loading conditions. The resulting measurements help determine important material properties such as yield strength, tensile strength, elongation, and elastic modulus.

The TTM-5L Single Column Universal Testing Machine generates controlled mechanical force through a precision moving crosshead driven by an AC servo motor. The motor operates through a synchronous cog-belt reducer connected to a high-precision ball screw. As the ball screw rotates, it converts rotary motion into smooth and controlled linear crosshead movement.

A precision load cell positioned within the load path measures the applied or reaction force, while displacement and deformation sensors monitor specimen movement. During a tensile test, the system records force and deformation continuously and uses the collected measurements to generate a stress-strain curve. Analysis of this curve provides key mechanical properties, including yield strength, tensile strength, proof strength, and elastic modulus.

Closed-Loop Testing Method

The DSC-10TT full-digital closed-loop control system continuously monitors the actual test conditions against the programmed target values. It measures force, deformation, or displacement and adjusts the AC servo motor output whenever a difference occurs between the measured and commanded values.

This feedback-based control allows the TTM-5L to maintain precise testing rates throughout the procedure. Operators can also switch between force control, deformation control, and displacement control during a single test when required by the selected test method.

Maintaining a controlled loading or deformation rate is important because the measured mechanical properties of some materials can vary with strain rate. For example, tensile testing methods such as ISO 6892-1 specify controlled testing rates to improve consistency and comparability between test results.

High-Resolution Measurement

The TTM-5L features a high-resolution measurement system designed to support its accuracy class 0.5 performance. Three 24-bit analog-to-digital acquisition channels measure load, displacement, and deformation with an effective resolution of up to 1/300,000 of full scale.

The system uses parallel signal sampling to capture measurement channels simultaneously. This synchronized acquisition helps maintain accurate relationships between load, deformation, and displacement throughout the test.

When an extensometer is connected, the DSC-10TT software analyzes the recorded test data and automatically calculates important material parameters, including ReH, ReL, Rp0.2, Fm, Rm, and E, along with other configurable results. Once the required yield-stage measurement is complete, the system can switch from deformation measurement to displacement collection, allowing the extensometer to be removed according to the test procedure.

Overall, the combination of precision mechanical motion, closed-loop control, synchronized high-resolution measurement, and automated data analysis enables the TTM-5L 5 kN Universal Testing Machine to deliver consistent and repeatable mechanical test results across a wide range of materials and applications.
