The instrumented plastic pendulum impact tester is an instrument for testing the impact resistance of materials under dynamic load. It is a necessary testing instrument for material manufacturers and quality inspection departments, and it is also an indispensable testing instrument for scientific research units to conduct new material research. Product Advantages: The appearance of instrumentation (more precisely, digital) pendulum impact testing machine has brought about significant changes in impact testing in two aspects. One is the main difference between the instrumented pendulum impact testing machine and the ordinary testing machine is instrumentation (digitization): that is, the control, energy display, and collection and processing of the impact curve are all digitized. The impact test results are visualized by graphical display, and curves of impact force-time, impact force-deflection etc. can be obtained; The second is the "standardization of instrumented impact test methods", which has caused a qualitative change in impact testing. This change is reflected in the following aspects: 1. The definition of impact energy is based on the definition of physical work: work=force×displacement, that is, the area under the impact force-deflection curve is used to measure; 2. The 13 parameters that reflect the impact performance of the material defined by the impact curve are 13:1 compared with the only one impact energy parameter given by the ordinary impact test method, which cannot be said to be a qualitative change; 3. Among the 13 performance parameters, there are 4 force, 5 deflection, and 4 energy parameters. They respectively indicate the performance indexes of the material's elasticity, plasticity and fracture process after being impacted, which is a sign of qualitative change in the impact test; 4. Visualize the impact test. It can also obtain the impact force-deflection curve like a tensile test. On the curve, we can visually see the deformation and fracture process of the impact sample; Features: 1. It can directly display the original curve, force-time, force-deflection, energy-time, energy-deflection, analysis curve and other curves. 2. The impact energy is automatically calculated according to the pendulum lift angle. 3. Calculate the four forces of inertial peak force, maximum force, initial force of unstable crack growth, and breaking force based on the measured values ​​of the force sensor; peak inertial deflection, deflection at maximum force, initial deflection of unstable crack growth, fracture deflection, total Five displacements of deflection; 14 results including energy at maximum force, initial energy of unstable crack growth, fracture energy, five energies of total energy, and impact strength. 4. The angle collection adopts high-precision photoelectric encoder, and the angle resolution is up to 0.045°. Ensure the accuracy of equipment impact energy. 5. The energy display device has two energy display methods, one is the encoder display, and the second is the force measurement by the sensor, and the computer software calculates and displays it. The two modes of this machine are displayed together, and the results can be compared with each other, which can completely eliminate possible problems. 6. Customers can configure different force sensors to impact the blade according to the test requirements. For example, the R2 blade meets ISO and GB standards, and the R8 blade meets ASTM standards.
