Structural Principle and Performance Features

The computer-controlled electronic universal testing machine mainly consists of the main frame, fully digital measurement system (load, displacement, deformation), servo system, computer control system with software package, and functional accessories.

Main Frame

The upper crosshead and the worktable are connected by four columns forming a portal-frame structure. A transmission mechanism is installed at the bottom of the worktable.

The transmission of the AC servo motor is reduced through a three-stage circular synchronous belt pulley system, which drives the ball screw to rotate and move the crosshead up and down. In addition to the ball screw guidance, guide columns also provide guidance for the moving crosshead. Thus, the simply supported beam structure of the moving crosshead becomes a fixed beam structure, increasing the rigidity by nearly three times.

The circular synchronous belt pulley and ball screw pair provide stable backlash-free transmission, enabling precise control of test force and deformation speed.

A photoelectric encoder is installed at the upper end of the screw for displacement detection of the moving crosshead. A limit mechanism is installed on the left cover plate to limit the movement range of the moving crosshead.

Speed control adopts an imported fully digital AC servo system. Through high-precision feedback, a full closed-loop control is formed. The system features a wide speed regulation range, fast response, and short positioning time. It also provides test force and deformation rate control functions.

The worktable, moving crosshead, and upper crosshead are all manufactured from high-quality steel plates through precision machining, which reduces vibration when the specimen fractures and improves overall rigidity.

Main Frame Features

The main frame adopts a portal-type prestressed structure with high rigidity, minimizing the influence of machine deformation on test results.

Circular synchronous belt pulley reduction and ball screw pair transmission are used to achieve backlash-free transmission, ensuring precise control of test force and deformation speed.

Stable transmission, fast response, and low noise.

Photoelectric encoder displacement sensor with high resolution and strong anti-interference capability.

Displacement protection system ensuring safe and reliable operation.

During assembly of the main frame and grips, strict control and adjustment are applied to ensure the coaxiality between the center hole of the load sensor on the moving crosshead and the positioning hole of the grip seat, as well as the coaxiality between the grip mounting shaft and the jaws. This ensures that the force application axis of the grips coincides with that of the testing machine, with an error controlled below 9%, which is far lower than the requirement of Grade 0.5 accuracy specified in GB/T 16491.
