YAW-300 microcomputer controlled electro-hydraulic servo pressure testing machine

YAW-300 microcomputer controlled electro-hydraulic servo pressure testing machine

Current Category: Electro-hydraulic Servo Tester

Features:
Host features:
The mainframe of the testing machine adopts a cast frame structure, and the whole machine has high rigidity.  
The loading system uses servo motors to control loading through servo oil pumps, ensuring fast response of system pressure and loading speed, no pressure overshoot, and good stability.
This machine adopts a column load sensor as the force measuring unit to ensure high testing accuracy;
measurement and control system
The measurement and control system includes servo measurement and control devices and software, with high control accuracy and good reliability. The measurement and control system can receive test instructions, sample numbers, sample sizes, and other sample information transmitted from the computer. The machine can automatically measure the test strength, compressive modulus of elasticity, compressive Poisson's ratio, and other related mechanical data of the sample, and communicate with the computer through a high-speed Ethernet communication interface. It has multiple control modes such as load loading, unloading, and holding, and can achieve smooth switching of control forms.
The controller adopts the 32-bit high-speed ARM chip of Cotex_M3 as the main control chip, which has high computing speed and data processing capability. It can realize the entire control process from data acquisition, PID operation, Ethernet communication to output control in a short time, thus achieving precise closed-loop control of the testing machine; The PID fuzzy control strategy is adopted to achieve closed-loop control of the load, which can realize functions such as constant speed loading, load maintenance, and constant speed unloading;
