What is a pendulum impact testing machine?
In industrial production and materials research, the pendulum impact testing machine is a common testing equipment used to evaluate the impact resistance of materials. This article will introduce in detail the definition, working principle, application fields and recent hot topics of the pendulum impact testing machine to help readers fully understand this equipment.
1. Definition of pendulum impact testing machine
The pendulum impact testing machine is a device that tests the impact resistance of materials through the impact force of a pendulum. It is widely used in quality testing and research in metals, plastics, rubber, composite materials and other fields. By simulating the impact conditions in actual use, the pendulum impact testing machine can provide key performance indicators such as toughness and brittleness of materials.
2. Working principle
The working principle of the pendulum impact testing machine is based on the law of conservation of energy. During the test, the pendulum is released from a certain height. After impacting the sample, the remaining energy pushes the pendulum to the other side. By measuring the initial energy and remaining energy of the pendulum, the energy absorbed by the sample can be calculated and its impact resistance can be evaluated.
