Fatigue Dynamic Testing Machine
Applications:
PWS-3 Electronic Fatigue Testing Machine is composed of main engine, electric actuator, servo motor,
electric cylinder, computer and software etc. It can be applied to dynamic performance and fatigue test of various materials, structural parts and components. It can be used for tensile, compression, dynamic low cycle fatigue, programmed fatigue, fracture mechanics and a variety of mechanical properties test.
The PWS series testing machine is the ideal equipment for dynamic testing in aerospace, aviation, transportation, metallurgy, scientific research institutes, colleges and universities.
◎ High Frame stiffness;
◎ The data acquisition system consists of four high precision 24 bit A/D conversion channels;
The highest resolution is 1/300000;
◎ Three-way photoelectric encoder input, allowing the pulse frequency of orthogonal code up to 5 MHZ;
◎ The electronic measuring system has no potentiometer and other hand-adjusting elements, which ensures interchangeability and facilitates maintenance and replacement;
◎ Built-in large-scale CPLD programmable device, with high-speed operation, real-time processing.
