The Functions And Main Testable Items Of Electronic Universal Testing Machines

Rubber, plastic, wires and cables, fiber optic cables, safety belts, belt composite materials, plastic profiles, waterproof rolls, steel pipes, copper profiles, spring steel, bearing steel, stainless steel (such as high hardness steel), castings, steel plates, steel strips, and non-ferrous metal wires are among the materials that can be tested with the electronic universal testing machine. Stretching, compression, bending, peeling, tearing two point stretch (needs an extensometer), and other tests are performed with it. The electromechanical integrated design of this machine is made up mostly of computers, force sensors, transmitters, microprocessors, load drive mechanisms, and color inkjet printers. Its great accuracy and sensitivity in detecting and managing loads and displacements is matched by its wide and precise loading speed and force measurement range. Additionally, it is capable of carrying out automatic control tests for constant displacement and constant loading. The styling, painting, and floor-standing model all take into account the pertinent ergonomic and current industrial design principles.

Factors Affecting The Functionality Of Electronic Universal Testing Machines

1.Host Section

In the event that the main engine is not installed in a level manner, it will result in friction between the working piston and the working cylinder wall, which will lead to errors. Typically exhibited as a positive difference, and the mistake that is produced as a consequence of the load gradually diminishes as the load increases.

2.Dynamometer Section

In the event that the force gauge is not installed in a level manner, it will result in friction between the swing shaft bearings, which will often be turned into a negative difference.

When it comes to measurements of small loads, the two types of mistakes described above have a relatively low influence, whereas when it comes to measurements of large loads, they have a pretty large impact.

1.Firstly, check if the installation of the testing machine is horizontal. Use a frame level to level the main engine in two directions perpendicular to each other on the outer ring of the working oil cylinder (or column).

2.Adjust the level of the force gauge on the front of the swing rod, align and fix the edge of the swing rod with the inner engraved line, and use a level to adjust the left and right levels of the body against the side of the swing rod.

The Main Testable Items Of Electronic Universal Testing Machines

The testing items of electronic tensile testing machines can be divided into ordinary testing items and special testing items. To determine the coefficient of material rigidity, the higher the ratio of the normal stress component in the same phase to the normal strain, the stronger and more ductile the material.

Common Testing Items For Electronic Tensile Testing Machines: (Common Display Values And Calculated Values)

1. Tensile stress, tensile strength, tensile strength, and elongation at break.

2. Constant tensile stress; Constant stress elongation; Constant stress value, tear strength, force value at any point, elongation at any point.

3. Extraction force, adhesion force, and peak value calculation.

4. Pressure test, shear peeling force test, bending test, pull-out force puncture force test.

Special Testing Items For Electronic Tensile Testing Machines:

1. Effective elasticity and hysteresis loss: On an electronic universal testing machine, when the specimen is stretched at a certain speed to a certain elongation or to a specified load, the percentage of work recovered during contraction and consumed during extension is measured, which is the effective elasticity; The percentage of the energy lost during the elongation and contraction of the sample compared to the work consumed during elongation is called the hysteresis loss.

2. Spring K value: This refers to the proportion of the force component that is in the same phase as the deformation to the total amount of deformation.

3. Yield strength: When the load at which the permanent elongation reaches a specific value under tension is divided by the initial cross-sectional area of the parallel component, the quotient that is obtained is the result.

4.Yield point: This point is referred to as the yield point, and it occurs when the material is stretched to the point where the deformation speeds up while the stress stays the same. When referring to the yield point, it is common practice to use the yield point that is located above the lower yield point. The yield point is divided into upper and lower yield points. The load will rapidly fall when it reaches the proportional limit and is no longer proportional to elongation. After that, the load will fluctuate up and down over a period of time, which will result in a considerable change in elongation. Yielding is the term used to describe this phenomena.

5. Permanent deformation:Despite the fact that the load has been removed, the material continues to possess deformation.

6. Elastic deformation: Once the load is removed, the material will no longer exhibit any signs of deformation.

7. Elastic limit:This refers to the maximum stress that a material is capable of withstanding without undergoing permanent deformation.

8. Proportional limit:The greatest stress that the load can sustain is the proportional limit, and it is possible for the load to maintain a proportional connection with elongation within a particular range.

9. Coefficient of elasticity, also known as Young's modulus of elasticity.
