measurement system

Load measurement: A 0.05% FS high stability and high-precision spoke type tension and compression sensor is selected, coupled with a high-precision measurement amplification system, to ensure high-precision measurement of the test force;

Sample deformation measurement: high-precision deformation measurement of the sample is achieved through a large deformation measurement system or an electronic extensometer (small deformation measurement), using a 24 bit A/D conversion acquisition system and computer data processing;

Measurement of crossbeam displacement: A 2000P/R high-precision photoelectric encoder is used to measure the displacement of the crossbeam (i.e. the absolute displacement of the upper and lower clamps) through a digital circuit after coaxial connection with a precision ball screw.

Transmission control system

Using an AC servo driver to control the rotation of the AC servo motor, the ball screw is driven by a synchronous belt to rotate and load, ensuring high transmission efficiency, low noise, smooth transmission, and speed accuracy within ± 1% of the indicated value.

loading frame

The frame structure is constructed by fixing the upper crossbeam and worktable with a guiding light bar, and the load is transmitted by the up and down movement of the middle crossbeam driven by a ball screw. It has the characteristics of reasonable structure, good stability, and smooth loading.
