HST-HFT-A SERIES 2-Column Hydraulic Servo Fatigue Testing Machine

Стандарты:

Functional Overview
It is mainly used to detect the static and dynamic mechanical properties of metal and nonmetal materials. It can realize mechanical tests such as tension, compression, tension-tension, compression-compression and tension-compression, as well as high-cycle fatigue, lowcycle fatigue, crack growth, fracture toughness and other tests, and realize various waveform outputs such as sine wave, triangle wave, square wave, etc.
