What is a joint tensile testing machine?
In the fields of modern industrial production and scientific research, the joint tensile testing machine is an important testing equipment used to evaluate the mechanical properties of materials, components or joints. With the rapid development of manufacturing and engineering technology, joint tensile testing machines have become more and more widely used and have become a key tool for quality control and safety assessment. This article will introduce in detail the definition, working principle, application scenarios and popular models of joint tensile testing machines.
1. Definition of joint tensile testing machine
The joint tensile testing machine is a special equipment used to measure the strength, deformation and fracture properties of materials or joints under tensile force. It applies controlled tension and records the stress and deformation data of the specimen to evaluate its mechanical properties. This equipment is widely used in metal, plastic, rubber, composite materials and other industries.
2. Working principle of joint tensile testing machine
The working principle of the joint tensile testing machine mainly includes the following steps:
1.Specimen fixed: Fix the joint or material to be tested in the upper and lower clamps of the testing machine.
2.Apply tension: Apply a gradually increasing tensile force to the specimen through a hydraulic or motor drive system.
3.Data collection: The sensor records the tensile force and the deformation of the sample in real time.
4.Result analysis: The software system generates force-displacement curves and calculates tensile strength, yield strength and other parameters.
3. Application scenarios of joint tensile testing machine
Joint tensile testing machines play an important role in multiple industries. The following are its main application scenarios:
| Industry | Application |
