What is a single-arm tensile testing machine?
In the fields of industrial production and scientific research, the single-arm tensile testing machine is a common material testing equipment and is widely used in testing the mechanical properties of metals, plastics, rubber, textiles and other materials. This article will introduce in detail the definition, working principle, application fields and recent hot topics of the single-arm tensile testing machine to help readers fully understand this equipment.
1. Definition of single-arm tensile testing machine
The single-arm tensile testing machine is an instrument used to measure the mechanical properties of materials under the action of external forces such as tension, compression, and bending. Its structural feature is that it has only one support arm, so it is called "single-arm type". This design makes the equipment smaller and easier to operate, making it suitable for use in laboratories and small production environments.
2. Working principle of single-arm tensile testing machine
The single-arm tensile testing machine applies tension or pressure to the sample through a motor-driven loading system. At the same time, it measures the force value and displacement through sensors, and finally calculates the strength, elastic modulus, elongation at break and other parameters of the material. Here are its core components:
| components | Function |
|---|---|
| Load system | Apply force via motor or hydraulic system |
| sensor | Measure force and displacement |
| control system | Control the test process and collect data |
| fixture | Fixed specimen |
3. Application fields of single-arm tensile testing machine
Single-arm tensile testing machines are widely used in the following fields:
| field | Application examples |
