GW-011 computer servo system type tension test machine

It is suitable for measuring mechanical properties and related physical parameters of various materials under tensile, compression, bending, shearing, tearing, stripping and puncture. It can be done by stretching, compression, three point bending, four point bending, shearing, tearing, stripping, finished shoe piercing, carton holding pressure, foam cycle compression, spring tension and pressure, and all kinds of dynamic and static cycle tests.
1.1 hardware

The main controller uses the most advanced 32 bit ARM processor in twenty-first Century. The processing speed reaches the level of the Pentium general computer. Compared with the traditional 8 bit MCU, the overall performance of the system is greatly improved, the speed of operation is faster and the control precision is higher.
The core component of the data acquisition is the latest ultra high precision 24 bit AD in the United States. The sampling rate can reach 2000 times per second, which can capture the instantaneous change process of power, and the whole process is up to 500000 degrees. The original 6 point calibration technology is used to further improve the accuracy, and the accuracy of force measurement is better than the national 0.5 level (superlative) standard.
The displacement encoder is counted by 4 frequency doubling technology, so that the displacement resolution can be increased 4 times, and the maximum can reach 0.0005mm.
Two output control modes of pulse and voltage can control any servo motor, frequency conversion motor or DC motor with pulse or voltage control interface to realize smooth and stepless speed regulation, and the output of switch quantity signal, such as rise, drop and stop, can be used to drive the external relay or solenoid valve directly, and can be used to control the DC motor. Or pneumatic, hydraulic and other power devices.
The advanced closed loop technology of speed, displacement and force can achieve precise arbitrary waveform control.
Rich interface Extensibility: up to 4 way 24 bit analog input, 3 way 16 bit analog output, 3 way pulse output, 3 AB phase photoelectric encoder input, 9 switch input, 8 way switch output, 1 USB interface, 1 RS232 interface, 1 path RS485 interface, 4 LCD interface, 1 parallel port micro printer interface, 1 serial port The mini printer interface has 1 8 * 4 matrix keyboard interfaces.
All input and output interfaces adopt high-speed photoelectric isolation technology, which has strong anti-interference ability.
