Impact Testing Machine For Instrumented Metal Pendulum JB-HC

Product Description:
The instrument of metal pendulum impact testing machine is the metal material in the dynamic load testing performance of the instrument, the use of full automation control, through the software to achieve the whole process, the impact of a large number of metal impact test, is a metal material manufacturers, quality inspection departments essential testing equipment, and scientific research units for new materials research indispensable test instrument.
Product advantage:
JBW-HC instrument (more accurate to say it should be digital) metal pendulum impact testing machine, so that the impact of the test in two aspects of a major change.
The main difference between the test machine and the common testing machine is the instrument (digital): control, energy display and impact curve of the acquisition and processing are realized. The impact test results were made by using graphic display to make the image, and the curve of impact force, impact force and displacement were obtained;
The second is the "standard test method for instrumented impact", it makes the change of impact test. This change is reflected in the following aspects:
1 the definition of impact power is defined by the definition of the physical work: the power = the force X displacement. Namely, the area under the impact force displacement curve is measured;
Compared to the 1 impact parameter test method of
2 parameter defined by the impact curve 13 reflects the impact strength of the composites with common shock given only 13:1, can not be said to be a qualitative change;
3.13 personality energy parameters, 4 force, 5 displacement, 4 energy parameters. They are showing performance of elasticity, plasticity and fracture process of materials after impact, this is a sign of change impact test;
4 make impact test image. It can also be used to get the curve of impact force and displacement, so that we can see the deformation and fracture process of the impact specimen in the curve;
5 increase in the impact parameters of the material toughness and brittleness: the success of the crack, the work of the crack propagation and the fracture toughness of the material. It makes us have a quantitative comparison of the toughness and brittleness of the material.
Function characteristic:
1The kinds of curves, such as time, force, displacement, energy, time, energy, time, energy, time, energy, force, energy, etc..
2, automatically according to the pendulum angle to calculate the impact power.
3. According to the force sensor, the yield stress, the maximum force, the unstable crack initiation force, the unstable crack growth, the crack initiation displacement, the maximum displacement, the unstable crack propagation, the unstable crack propagation, the total displacement of five displacement, the maximum force energy, the unstable crack propagation energy, the total energy of six C2, C3, C4, C1 four 19.
4, the machine is equipped with fully enclosed protective cover, to prevent the fracture of the specimen, can also prevent the test personnel to enter the test machine inside the test. Provide conditions for the user's security operation. Is the metal material manufacturers, quality inspection departments of the necessary testing equipment, but also the scientific research unit of new materials research indispensable test instrument.
5, the chassis and the base of the integrated casting processing, high stability, good rigidity, no assembly error. Front and rear symmetry, the pendulum is supported by a simple supported beam, the structure is simple and reliable, high precision, small energy loss, the pendulum swing without vibration, more suitable for high energy impact.
6. The design of the device is used to avoid the impact of the pendulum and the damage caused by it. It can reduce the noise and prolong the service life of the equipment and improve the safety.
7. High precision photoelectric encoder is adopted in the angle of view, and the angle resolution is as high as 0.045. Ensure the accuracy of the impact energy.
8, the energy display device has three kinds of energy display mode, a, the scale of the display, two, the encoder display, three, through the sensor test force, computer software calculation show. This machine is shown in three ways. The results can be compared with each other, which can eliminate the possible problems.
9, the customer can be configured according to the test requirements of different force sensor. Such as ISO, GB, R2, ASTM, R8 blade.
