Dual Channel and Balance Bar Fatigue Testing Machine

Product Description

1. Product Introduction

SDW-E100 microcomputer controlled double-channel compression and torsion testing machine is a new generation microcomputer controlled measurement and control system specially designed for universities and scientific research institutes. The computer system controls the rotation of the servo motor through the full digital controller and the two-way speed regulating system. After the deceleration system, the precision ball screw drives the moving beam to rise and fall, and the torsion of the loading head completes the test combination requirements such as tensile, torsion, compression torsion and so on. In addition, a wide variety of test accessories are configured. It has a very broad application prospect in the mechanical properties test of metal, non-metal, composite materials and products.

At the core of the system, the two sensors and the loading system are coupled with each other and do not affect each other during the test.
