What is a tensile strength testing machine?
In industrial production, materials research and quality control, tensile strength testing machine is an indispensable equipment. It is used to measure the tensile strength, yield strength, elongation and other mechanical properties of materials, and is widely used in metal, plastics, rubber, textiles and other industries. This article will introduce in detail the definition, working principle, application fields and comparison of popular models in the market of tensile strength testing machines.
1. Definition of tensile strength testing machine
A tensile strength testing machine, also known as a tensile testing machine or universal material testing machine, is a device used to test the mechanical properties of materials under tensile force. By applying tensile force, the deformation and fracture process of the material is recorded, thereby calculating key parameters such as tensile strength and elastic modulus.
2. Working principle
The working principle of the tensile strength testing machine mainly includes the following steps:
1.Hold sample: Fix the material to be tested in the upper and lower clamps of the testing machine.
2.Apply tension: Applying gradually increasing tensile force to the sample through a motor or hydraulic system.
3.Data collection: The sensor records the tensile force and deformation of the sample in real time.
4.Analyze results: The software system generates stress-strain curves based on the collected data and calculates mechanical performance parameters.
3. Application fields
Tensile strength testing machines have important applications in many industries. The following are its main application areas:
| Industry | Application scenarios |
