Tensile test function for rubber, plastics, textiles, wire and cable, composite materials, leather, waterproofing membranes, non-woven fabrics, geotextiles, paper and other non-metallic materials and wire, metal foil, sheet metal and metal bars, etc. Tests such as stretching, squeezing, bending, peeling, shearing, etc., have many characteristics such as wide measuring range, high precision, fast response, etc., and can stop the real-time display and printing of experimental data. Universal testing machine is widely used in quality monitoring, teaching and scientific research, aerospace, steel and metallurgy, automotive, construction and building materials.
Although universal testing machine is used as the most commonly used mechanical testing instrument in the laboratory and its use is very common, we must understand what is the duty principle of universal testing machine and the structure of universal testing machine system.
1. The control system of the universal testing machine is a system that controls the operation of the experimental machine. People can control the operation of the experimental machine through the console. After the display screen, the shape of the experimental machine and various experimental parameters can be known. If the device is connected to a computer, It can be used by the computer to complete various functions and to stop data processing analysis and print the experimental results. The communication between the experimental machine and the computer is usually using RS232 serial communication. It stops the communication through the serial port of the computer. This technology is mature, reliable, and easy to use.
2. The drive system of the universal testing machine is mainly used to move the crossbar of the experimental machine. Its duty principle is to control the motor by the servo system. The motor drives the screw to rotate through a series of transmission mechanisms, such as a gearbox, to reach the purpose of controlling the movement of the crossbeam. After changing the speed of the motor, the speed of the beam can be changed.
Third, universal testing machine measurement system 1, the principle of beam displacement measurement and deformation measurement is roughly the opposite, are measured by the number of optical encoder output pulse to obtain the beam displacement.
2. Measure the force through the force sensor, signal reducer and data processing system to complete the measurement. The most commonly used force sensor is the strain gauge sensor. The so-called strain gauge sensor is composed of a strain gauge, an elastic element and a compensating element, a protective cover, a wiring socket, and a loader, and can convert a mechanical quantity into a power output device. Strain gauge pull and pressure sensors are available in a variety of types, including cylindrical, spoke, S double-hole, and cross beam sensors.
3. Deformation measurement The deformation measurement device has two chucks, which are connected together with a photoelectric encoder mounted on the top of the measurement device through a series of transmission mechanisms. When the distance between two chucks changes, the axis of the photoelectric encoder is driven. Rotation, http:// photoelectric encoder will have a pulse signal output. The disposal of this signal by the disposer can then result in the deformation of the sample.
