Product Details
PWS-200Dynamic and Static Testing System
1. Overview:
Electro-hydraulic Servo Fatigue Testing Machine<Abbreviated as Testing Machine> is mainly used to test the dynamic characteristics of metals, non-metals, and composite materials under room temperature (or high/low temperature, corrosive environment). The testing machine can perform the following tests:
- Tensile, compressive, and shear fatigue durability tests
- Crack propagation tests
- Fracture toughness
It consists of an electrical controller, servo valve, load sensor, displacement sensor, extensometer, and computer, forming a closed-loop servo control system that can automatically and accurately control the testing process and automatically measure test parameters such as test force, displacement, and deformation.
The testing machine can achieveIt can generate waveforms such as sine wave, triangle wave, square wave, and sawtooth wave, and can conduct mechanical tests such as tension, compression, bending, low-cycle, and high-cycle fatigue. It can also be equipped with environmental testing devices to complete environmental simulation tests at different temperatures.
The testing machine is flexible and convenient to operate, with the movement of the crossbeam, locking, and sample clamping all completed by button operation. It uses advanced hydraulic servo drive technology for loading, high-precision dynamic load sensors, and high-resolution magnetostrictive displacement sensors to measure the force and displacement of the specimen. The fully digital measurement and control system achievesforce, deformation, displacementPID control, with smooth transitions between controls., the testing software operates inWINDOWS XP/Win7 Chinese environment, with powerful data processing capabilities, automatically saving test conditions and results, displaying and printing them. The entire testing process is under computer control, making the testing machine an ideal high-cost-performance testing system for research institutes, metallurgy construction, national defense military industry, colleges and universities, mechanical manufacturing, transportation, and other industries.
The testing machine can conduct dynamic high/low cycle fatigue tests, program-controlled fatigue tests, as well as static tests under constant rate, constant strain, and constant stress control, and various conventional mechanical performance tests. It can also perform fracture mechanics tests, and if needed, can conduct partial vibration and impact tests, as well as fatigue life, crack propagation, and fracture toughness performance testing of materials or components in a broad sense, safety evaluation of actual specimens, and working condition simulation.
