What is a bending testing machine?
With the continuous development of industrial technology, bending testing machines, as an important material testing equipment, are widely used in metal, plastics, composite materials and other industries. This article will introduce in detail the definition, working principle, application fields and recent hot topics of the bending testing machine to help readers fully understand this equipment.
1. Definition of bending testing machine
Bending testing machine is a special equipment used to test the performance of materials under bending load. It simulates the bending state of materials in actual use to evaluate their mechanical properties such as flexural strength, elastic modulus, and fracture toughness. Bending testing machines usually consist of a loading system, a control system and a data acquisition system, which can accurately control the loading force and displacement and record test data in real time.
2. Working principle of bending testing machine
The working principle of the bending testing machine is to measure the bending properties of the material by applying bending force to the sample to cause it to deform. The specific steps are as follows:
1.Sample preparation: Process the material to be tested into a specimen of standard size.
2.Load: Place the sample on the support base of the testing machine, and apply bending force through the loading device.
3.Data collection: Record the bending deformation and loading force of the sample in real time and generate a force-displacement curve.
4.Result analysis: Calculate the flexural strength, elastic modulus and other parameters of the material based on the test data.
3. Application fields of bending testing machine
Bending testing machines are widely used in the following fields:
| Industry | Application scenarios |
