Servo fatigue testing machine
1. Application
This series computer Control Electro-hydraulic Servo Fatigue Testing Machine is ainly used to detect a variety of metals, non-metallic materials and small movable member, the static mechanical properties test. It can do tensile, compression, bending, low cycle and high cycle fatigue, crack growth, fracture mechanics test under sine, triangle, square wave, trapezoidal wave, random wave, combination waveform.
This Test machine is flexible, moving beam down, locking the sample holder by button operations, the use of advanced hydraulic servo drive technology loaded, high precision and high resolution dynamic load sensor magnetostrictive displacement sensor specimens force values and displacement.
