What is a torsion force testing machine?
In the fields of industrial manufacturing, material science and product quality inspection, the torsion force testing machine is an important testing equipment. It is mainly used to measure the performance of materials or products under torsional force, such as torsional strength, torsional stiffness and fatigue life. This article will introduce in detail the definition, working principle, application scenarios and comparison of popular models in the market of torsion force testing machines.
1. Definition of torsion force testing machine
A torsion testing machine is a special equipment used to test the torsional properties of materials or components by applying torque. It can simulate torsional conditions in actual use and help engineers and researchers evaluate the reliability and durability of products.
2. Working principle
The torsion testing machine drives the fixture to rotate through a motor or hydraulic system to apply torque to the specimen. At the same time, the sensor measures the torque and torsion angle in real time, and the data is transmitted to the computer for analysis and processing. The following are the core parameters of the torsion force testing machine:
| parameters | Description |
|---|---|
| Maximum torque | The maximum torque value that the equipment can exert, usually in N·m |
| Twist angle range | The maximum torsion angle that the device can measure, usually ±360° |
| Test speed | The rate at which torque is applied, usually in °/min |
| Accuracy level | Accuracy of torque and angle measurements, usually Class 0.5 or Class 1 |
3. Application scenarios
Torsion testing machines are widely used in the following fields:
| Industry | Application |
|---|---|
| automobile manufacturing | Test the torsional performance of drive shafts, steering systems and other components |
| Aerospace | Assess torsional fatigue of aircraft engine blades and fuselage structural parts |
| medical device | Test the torsional strength of orthopedic implants and surgical instruments |
| Materials research | Study the torsional mechanical properties of metals, plastics, composite materials, etc. |
4. Comparison of popular models in the market
According to market research data in the past 10 days, the following is a performance comparison of several popular torsion testing machines:
| Model | brand | Maximum torque (N·m) | Accuracy | price range |
