Universal material testing machine
[Feilong Jiangli Edition]The universal material testing machine is also called universal tensile machine or electronic tension machine. Independent servo loading system, high precision broadband electro-hydraulic servo valve to ensure high precision, high efficiency, low noise, fast response; the use of independent hydraulic clamping system to ensure that the system runs smoothly with low noise, and the test process sample firmly clamped, not slipping. The universal material testing machine is a digital wide frequency electro-hydraulic servo valve controlled by a microcomputer to drive a precision hydraulic cylinder. The microcomputer control system can automatically control the testing force, displacement and deformation in various modes, and complete the tensile, compressive and bending tests of the samples. It meets the national standard GB/T228-2010 "Room Temperature Tensile Test of Metal Materials" Requirements of the law and other standards.
It is suitable for tensile test of rubber, plastic, textile, waterproof material, wire and cable, mesh rope, wire, metal bar, metal plate and other materials. Additional accessories can be used for compression, bending, ring stiffness test.
It is mainly composed of force sensor, servo driver, microprocessor, computer and color inkjet printer. High precision servo speed motor can be set up stepless speed. All the integrated components are joined by plug mode. The principles of modern industrial design and ergonomics are fully taken into account in floor-mounted models, modeling and painting.
Adopting high speed DSP platform, it has high integration, powerful control, data processing ability and high reliability. Adopting the full digital, force, deformation and displacement control system of self-adaptive PID algorithm, it realizes the full digital control of force, deformation and displacement. The control loops can be switched automatically, and the speed control of test force, deformation and displacement can be carried out. USB 2.0 communication, plug-and-play interface This interface can realize hot plug-and-play, that is, plug-and-play function. The system board adopts the unique anti-jamming wiring method of four-layer PCB. The whole control system has high performance-price ratio and high reliability. The whole test process is controlled by microcomputer. The load value, displacement value, deformation value, test speed and test curve are displayed dynamically and real-time. Line. The test results can be automatically saved and re-adjusted after the test. The test process can be reproduced through curve traversal. The test software under the Chinese Windows platform has strong data and graphics processing function. It can print out the complete test report and curve immediately. It has perfect protection functions such as limit protection, overload protection and emergency stop.
