AEW-B Series Microcomputer Control Hydraulic Universal Testing Machine

I. Main Purpose

AEW-B series microcomputer control hydraulic universal testing machine can be used for testing of mechanical properties such as tensile, compression, bending and shearing of metal and nonmetal materials, can achieve the closed loop control over testing force, displacement, deformation, stress and strain and can edit the control modes independently. With more than one hundred standard modes inside it, the machine can carry out the analysis on data fully according to the standard requirement and achieve print and internet transmission of the test results.  

II. Functional Features

This testing machine adopts micro-computer controlled fully digital broadband hydraulic Digital Valves to drive the precision hydraulic cylinder, achieve automatic control in various modes over testing force, displacement and deformation and carry out tensile, compression and bending tests on the specimen according to national standards and other standards.

■ The main machine of the testing machine adopts underneath hydraulic cylinder. Power for adjusting the test space and the transmission are mounted at the bottom of the testing machine, which provides stable transmission. Upper and lower jaw holds are fully-open structures. Specimens can be clamped conveniently via the automatic hydraulic clamping system with good stability.

■ Clearance adjusting mechanism allows the movable beam in the most reasonable operating position and strained condition.

■ With relevant attachments configured, tests on samples such as reinforced bars, steel strand, cable, fasteners and concrete can be conducted via this testing machine.

■ The hydraulic clamping device can adjust the clamping speed independently (the inching clamping device can be configured according to the customer requirements)

■ Load sensors or oil pressure sensors can be selected independently, improving effectively the test range and the force accuracy.

■ The underneath structure of the oil cylinder can reduce the height of the main machine, lower the test center of gravity and reduce the damage of the rupture impact force to the machine.

■ Photoelectric encoders can measure the movement distance of the beam.

■ The integrated oil source design makes the whole machine more compact and reasonable, reducing the floor area.

■ Double control system of manual and automatic is provided and the operation mode can be selected independently.

■ The built-in control card based on PCI technology reduces connection, improves the function of real-time control over the test and real-time acquisition and improves the stability of the product.

III. Introduction of Software

Input of specimen information:

The human-machine interface is adopted to analyze, calculate and test the indexes on mechanical properties of the material and calculate automatically elastic modulus, yield strength and non-proportion elongation stress etc. after the test is completed. It is visualized and convenient, improving the analysis accuracy.
