What is a cantilever beam impact testing machine?
The Izod impact testing machine is a special equipment used to test the impact resistance of materials under impact load. It is widely used in the quality control and research fields of plastics, composite materials, metals and other materials. By simulating the impact conditions in actual use, the Izod impact testing machine can evaluate the toughness, brittleness and impact resistance of materials, providing a scientific basis for material selection and application.
Working principle of Izod impact testing machine
The working principle of the Izod impact testing machine is to release the pendulum to impact the specimen fixed on the fixture at a certain speed and energy. After impact, the remaining energy of the pendulum is calculated from the angle or height difference, giving the energy absorbed by the specimen. This energy value directly reflects the impact resistance of the material.
Application fields of Izod impact testing machine
Izod impact testing machines are widely used in the following fields:
| field | Application examples |
