Introduction:
The ETM-100 is a new generation microcomputer-controlled electronic universal testing machine. It is primarily used for testing mechanical properties such as tension, compression, flexure, shear, peel, and tear on a variety of metals, non-metals, and composite materials. The system utilizes microcomputer closed-loop control, boasting a wide and accurate loading speed and force range, and provides high precision and sensitivity in load and displacement measurement and control. This equipment is suitable for use in the metal, adhesive, pipe, profile, aerospace, petrochemical, waterproofing membrane, wire and cable, textile, fiber, rubber, ceramic, food, pharmaceutical packaging, geotextile, film, wood, and paper manufacturing industries, as well as in product quality control departments at all levels. It is also suitable for teaching demonstrations in universities and colleges.
The main unit of the testing machine is designed for aesthetics, ease of operation, stable and reliable performance, and is pollution-free, low-noise, and highly efficient. The auxiliary fixtures are designed to match the main unit, featuring a wedge-shaped, translational structure and manual rotary clamping, ensuring that specimens are not subject to additional forces. The clamping is convenient, reliable, and slip-resistant. This testing machine utilizes a digital AC servo speed control system and motor with high speed regulation accuracy and stable performance. A specially designed synchronous toothed belt reduction system and ball screw assembly drive the testing machine's moving crosshead. The Windows-based database-based control and data processing software utilizes virtual instrumentation, replacing traditional digital tubes and oscilloscopes, enabling on-screen display of test force, peak force, crosshead displacement, specimen deformation, and test curves. All test operations can be completed on the computer screen using mouse input, providing a user-friendly human-machine interface. A dual-channel, fully digital programmable amplifier, integrated within the PC, enables true physical zeroing, gain adjustment, and automatic shifting, zeroing, and calibration of test force measurement without any analog adjustment steps. The highly integrated control circuitry eliminates mechanical adjustment devices such as potentiometers, resulting in a simple structure and reliable performance. The combined application of these technologies ensures closed-loop control of test force, specimen deformation, and crosshead displacement, enabling tests involving constant force, constant displacement, constant strain, constant velocity load cycles, and constant velocity deformation cycles. The PC-based expert system allows users to independently set control modes such as constant stress, constant strain, and constant displacement, with smooth switching between them. The programmable mode meets the requirements of national standards GB/T228-2010, "Metallic Materials - Room Temperature Tension Test Method," and GB/T7314-1987, "Metal Compression Test Method," enabling data processing in accordance with various standards, including GB, ISO, JIS, ASTM, and DIN. The system offers excellent scalability, with processed results stored on disk in ASCII format. This facilitates post-processing, such as test data reanalysis, database management, and network transmission.

Because the testing machine implements automated test process control and computerized test results processing, operators can easily and independently set test program steps. During tensile testing, the operator can clearly observe the entire test process for materials such as mild steel and cast iron. By repeatedly loading at different curve segments, the force-displacement (deformation) curve can be used to visually verify Hooke's law and observe cold work hardening. For materials without obvious physical yield, the hysteresis loop method or successive approximation method can be used to determine the specified non-proportional elongation strength. During the compression process, it is convenient to observe the compression yield and strengthening phenomena of mild steel, and the compression failure process and fracture shape of cast iron. It can also test the n and r values of mechanical materials.
Structure and Principle:
The main unit consists of an upper crossbeam, a moving crossbeam, and a workbench connected by columns and ball screws to form a rigid floor-standing frame structure. An AC servo motor and AC servo speed control system are installed below the workbench. The AC servo motor drives the dual ball screws through a synchronous toothed belt reduction mechanism, which in turn drives the moving crossbeam up and down to load the specimen. (Compression and bending fixtures are installed between the moving crossbeam and the workbench to perform compression and bending tests on metal or non-metallic specimens; a tensile fixture is installed between the moving crossbeam and the upper crossbeam to perform tensile tests on metal or non-metallic specimens.) The load cell, mounted below the moving crossbar, measures the test force. The AC servo motor has a built-in displacement measurement system that measures specimen displacement, which can also be used to approximate specimen deformation. For some metal materials, the testing machine is equipped with a dedicated extensometer, a device for measuring specimen elongation. The extensometer's dual grips clamp the specimen at two points along the gauge length, measuring the separation distance between the two points in real time, representing the specimen deformation. A microcomputer (PC or LCD microcontroller) controls the test process and provides data processing and output.

Operating Conditions:
1. Room temperature 10-35°C.
2. Relative humidity ≤ 80%.
3. No vibration, corrosive media, or strong magnetic fields.
4. Power supply voltage fluctuations not exceeding 10% of the rated voltage.
5. Mount horizontally on a stable foundation with a levelness of 0.2/1000.
 Performance and features:
1) The test process is controlled by an AC servo motor and AC servo speed control system, significantly improving control accuracy and quality. The system is stable, efficient, and low-noise (virtually silent at low speeds). The control speed range is significantly widened (0.005-500 mm/min), making it suitable for both low-speed testing of conventional materials (such as metals, cement, and concrete) and high-speed testing of non-metallic materials (such as rubber). It also allows for rapid adjustment of the test space when no load is applied, saving time for auxiliary testing. This test speed meets current domestic testing speed requirements for all conventional metal and non-metallic materials.
2) The reduction mechanism, comprised of a powerful combination of a synchronous toothed belt and a precision ball screw, results in a simpler and more efficient structure, significantly improving transmission efficiency. The lower worktable height of the main machine is also reduced, resulting in a more coordinated appearance.
3) The dual-chamber structure, with independent tension and compression chambers, facilitates operation and eliminates the tedious task of swapping test fixtures when performing tension, compression, and bending tests in the same chamber.
4) Sensors of varying specifications can be configured upon request, significantly expanding the test range to meet the measurement requirements of varying test loads. 1) The main unit features an aluminum alloy housing with an elegant and aesthetically pleasing design.
2) Utilizing advanced control technology, it offers three closed-loop control modes: stress, strain, and displacement. Each control loop can automatically switch between them, achieving a smooth, impact-free transition between modes. Test force, peak value, displacement, velocity, test status, and test curves can be displayed simultaneously.
3) Test force, deformation, and displacement rates can be controlled and maintained.
4) The crosshead can be adjusted to fast or slow during specimen clamping, offering flexible and flexible operation.
5) It features a function that returns to its initial position after the test, ensuring high efficiency and speed.
6) It features comprehensive limit protection, overload and overcurrent protection, and automatic shutdown upon test failure, ensuring reliability and safety.
7) A robust, in-house test database allows for the storage, query, and recall of test data at any time.
8) Multiple report printing interfaces are provided, allowing users to edit and print reports in any format as needed.
9) The entire control system offers high cost-effectiveness and reliability. 10) Conduct tensile tests on materials according to national standards or user-provided standards, compile and process test data, and then output and print various test curves and test reports. Selectable test curves such as load-time, load-displacement, displacement-time, and deformation-time can be displayed in real time, zoomed in, compared, and traversed, allowing for process monitoring. Intelligent and convenient.
11) Professional users can flexibly add required standards using the "Standard Add-in Editor" software.
12) This fully Chinese Windows-based testing software features powerful data and graphics processing capabilities, instantly printing complete test reports and test curves. A data interface is available for direct connection to the company's (laboratory's) integrated information management network.
