Damper Torsion Testing Machine
Category：Torsion Testing Machine
Introduction
A damper is only a component. When used in different locations or under different working conditions, it provides different damping effects. Damper is used for vibration reduction; Snubber is used for shock protection, allowing movement at low speeds, but locking and forming a rigid support when the speed or acceleration exceeds the corresponding value.
Application
The Material Torsion Testing Machine is mainly used for torsion tests of materials. It adopts manual loading, a high-precision torque sensor for torque measurement, and a photoelectric encoder for rotation angle measurement, with digital display of test results. It is mainly suitable for research institutes, universities, colleges, and mechanical laboratories of industrial and mining enterprises to determine the torsional properties of materials.
