What is a digital torsion testing machine?
In the fields of industrial manufacturing, material science and product quality inspection, the digital torsion testing machine is an important testing equipment. It is mainly used to measure the mechanical properties of materials or parts under the action of torsional force, such as torsional strength, torsional stiffness and breaking torque. This article will introduce in detail the definition, working principle, application fields and recent hot topics related to the digital torsion testing machine.
1. Definition of digital torsion testing machine
Digital display torsion testing machine is a testing equipment that monitors and records torsion force in real time through digital display technology. It usually consists of a loading system, sensors, data acquisition system and control system. It can accurately measure the mechanical parameters of the material during the torsion process and display them directly on the digital screen.
2. Working principle
The working principle of the digital torsion testing machine is to apply torsion force to the sample through a motor or hydraulic system, and at the same time collect data in real time through a torque sensor and an angle sensor. This data is processed, displayed in digital form on a screen, and can be further analyzed by software.
