　　4、 Scheme description

　　1. Host

1.1 The host adopts a high-strength portal frame structure, which has high strength and small deformation;

1.2 Adopting imported high-precision ball screws for efficient and stable transmission;

1.3 The transmission part adopts circular arc toothed synchronous belt transmission, and there is no gap in both directions during the transmission process;

1.4 Adopting AC servo motors and drive systems to ensure smooth transmission and stable torque, equipped with overcurrent, overvoltage, overload and other protection devices, with a speed ratio of up to 1:100000;

The fixture is specially designed to hold firmly, easy to operate, and without any slipping of the jaws;

1.6 Special process ensures the coaxiality of the testing machine, effectively eliminating the influence of irregular samples on the sensor.

2. Control system

The STC300 fully digital closed-loop measurement and control system has many unique features and technological innovations, mainly reflected in:

2.1 Four closed-loop controls have been implemented for test force, specimen deformation, beam displacement, and test process;

2.2 The data acquisition system consists of 4 high-precision 24 bit A/D conversion channels. The resolution reaches 1/300000, and the entire process is not divided into different levels;

2.3 Select original integrated components such as BB, AD, Xilinx, etc., with fully digital design;

2.4 Compliance with PCI bus standards, automatic recognition and installation by microcomputer, achieving "plug and test";

2.5 The electronic measurement system does not have analog components such as potentiometers, ensuring interchangeability and facilitating maintenance and replacement.

control software

Compliant with more than 30 national standards such as GB17657-1999, GB228-87, GB228-2002, etc., it can also conduct tests and data processing according to various standards provided by GB, ISO, JIS, ASTM, DIN and users, and has good scalability.
