UTM Microcomputer-controlled Electronic Universal Testing Machine

Main use

This machine can perform mechanical property testing and analysis on metals, non-metals, and composite materials. It is widely used in industries such as aerospace, petrochemicals, machinery manufacturing, plastics and rubber, ceramics and building materials, metal materials, construction engineering, as well as in institutions of higher education, research organizations, technical supervision, and quality inspection stations.

Different fixtures can be selected according to GB/ISO/ASTM/JIS/DIN standards to perform tension, compression, bending, peeling, shearing, tearing, piercing, and bursting tests, measuring parameters such as yield strength, tensile (compressive, bending) strength, elongation, non-proportional strength, and elastic modulus.

The control system software is based on the Windows operating system, offering fast operation, a user-friendly interface, and simple operation. It can meet the testing and measurement needs of different materials. If required, the software can be customized and its functions expanded according to user requirements.

Measurement system:

Load measurement: A 0.05% FS high-stability, high-precision wheel-spoke tension-compression sensor is used, combined with a high-performance measurement amplification system, ensuring high resolution of test force.

Measurement of specimen deformation: Achieved through a large deformation measurement system or electronic extensometer (for small deformation measurement), using a 24-bit A/D conversion microcontroller data acquisition system, controlled by a computer for data processing.

Displacement measurement: A 2000P/R high-precision optical encoder is coaxially rotated with a precision screw to measure displacement (i.e., the relative displacement between upper and lower jaws) through a digital circuit.

Drive Control System

The machine adopts a dual-space portal structure, with the upper space for tension and the lower space for compression and bending. The main frame consists of columns, upper beam, middle beam, and worktable. The speed control system, located beneath the worktable, uses a high-precision, wide-range, and stable servo motor to drive the ball screw pair via a synchronous toothed belt reduction system. The ball screw pair drives the middle beam, enabling the tensile (or compression/bending) fixtures to move up and down to apply and release load on the specimen. This design offers advantages of high rigidity, high efficiency, and stable transmission.

Test Force Control System

It adopts computer and advanced electronic technology to achieve standardized and modular control, featuring smooth loading, accurate measurement, and high sampling frequency. It automatically collects and processes test data, draws various curves, and prints test reports.

Protective device

Equipped with protection functions such as overload, overcurrent, and leakage.
