Equipment Description:

The PLW-100 microcomputer controlled electro-hydraulic servo fatigue testing machine is mainly used for tensile and compressive fatigue testing, fracture toughness testing, fatigue crack propagation testing, low cycle fatigue testing, three-point bending fatigue testing, CT testing, CCT testing, etc. of metal materials and their components, rubber elastic elements, shock absorbers, etc. under waveform states such as sine wave, triangular wave, square wave, trapezoidal wave, and oblique wave.

The mainframe of the testing machine adopts a high stiffness frame design, and the crossbeam adopts a hydraulic lifting method to adjust the testing space. The precision guided actuator and intelligent testing software TestLive are used to ensure complete and accurate testing results.

Functional features:

Adopting "CPU+DSP" dual core control, bus slot architecture, easy expansion, and excellent dynamic performance.

Communication with computers uses USB or Ethernet ports (RJ45), which have high data transmission rates and enable real-time software data processing.

Bus slot architecture, which can expand and connect multiple sensors.

The high-speed sensor data acquisition card ensures high-speed response of dynamic control and accurate data sampling.

Displacement, load, and deformation closed-loop control achieve smooth control switching between each other.

Built in function generator for controlling sine waves, triangular waves, trapezoidal waves, oblique waves, etc.

Each measurement channel synchronously samples and measures, resulting in more realistic test results.

Closed loop control is fast and high-frequency, achieving complete dynamic control characteristics.

The electrical design meets the requirements of EMC safety standards.

The sampling and control frequency is stable, ensuring the accuracy of data and control.

It has limit protection and full range overload protection functions.
