Computerised Universal Testing Machine , Hydraulic Compression Testing Machine

Model: IN-300AD/600AD/1000AD

Purpose:

Microcomputer screen display hydraulic UTM mainly adopts four-standard column main machine of underneath-type oil cylinder, used for tensile, compression, bending and shearing test for metal and non-metal materials. It applies to various fields including metallurgy, construction, light industry, aviation, aerospace, material, institutions of higher education and scientific institutions, etc.

Its test operation and data process meet requirements of standard GB228-2002 “Material in room temperature: test method of metal tensile”.

Specification:

Description Schemes:

1. The main machine

The main machine adopts underneath type of oil cylinder, tensile space is above the main machine, compression and bending space is between the lower cross beam and working station.

Solid four-standard column and two-lead screw structure design, so the whole machine has strong stability.

There designs a sliding plate of 10mm between jaw and jaw splint, effectively extending service life of jaw splint.

Structure principle

2. Hydraulic system (table-type oil source)

(1) Hydraulic principle:

As shown in figure 2, it is load-adaptive meter in speed control system.

Hydraulic oil in the fuel tank enters into oil circuit when the motor drives the oil pump, it flows through non-return valve, 10μhigh-pressure filter, differential pressure valve group and servo valve to enter into oil cylinder. The computer sends out signal to the servo motor, to control the mouth and direction of servo valve, so as to control the flow entering into the oil cylinder, realizing control of uniform-speed test force and displacement.

Figure 2: hydraulic principle

(2) Features:

It adopts high-pressure oil pump, with low noise and steady pressure.

It adopts integrated design for dynamic system and operating platform, easy to operate and saving test space at the same.

The surface is disposed with spraying plastics, so the appearance is nice.

Control system:

Full-digital measurement and closed loop control system has many advanced characteristics and technological innovation, mainly reflected in:

Realizing closed loop control system control of testing force, specimen deformation, cross-beam displacement and test process.

Data collecting system is composed of 4-path high precision 24-bit A/D shift channels, the maximum resolution ratio reaches 1/300000, the whole process is stepless.

It adopts original famous-brand integrated components like BB, AD and Xilinx, with full-digital Design.

It conforms to PCI bus standard, the microcomputer is automatic identification and installation for microcomputer, achieving “plug and test”.

There is no analogue element like potentiometer for electronic measurement system,guaranteeing interconvertibility and convenient for maintenance and replacement.

Control software:

It conforms to more than 30 relevant regulations of national standards like GB228-87,GB228-2002.

1. Computer control system: it has advantages of high integration level, stable performance and convenient adjustment. Can carry out real-time

collection for test data and real-time dynamic display for test characteristics curve; test data file can be saved by the method of Access

common database or SQLserve large database, which is convenient for achieving users’ resource sharing and network management, and

reanalysis.

This software have an easy access to various word2000 reports users defined, solving the problem that different users or one same user has

different requirements for the reports in different times, and it can deal with original data of test force, displacement and time and their

derived curves.

2. Protection function: this tester has limit protection of software and machine, can dynamically set the ratio of automatic stop exceeding

maximum load; it has overcurrent, overvoltage, overload and other protection functions.

3. Can realize automatic mark for load channel, intuitive and convenient.

4. Batch test can realize classified display for curve, and curve follows automatically.

5. This software can realize speed set user defined, and speed adjustment by computer. It can also realize high precision speed mark, and
adjusts speed stage and code at any time.

6. Monitoring test process: can realize real-time display for various parameters like test force, displacement and curves in the test.

7. Hierarchical management function for software permissions: to improve safety of software and data, this software can realize hierarchical

management function by setting different passwords protection.

8. Result representation function: after finishing and saving test, users can open it at any time in the future and reanalyze test data according to

need.

9. Users can select load-time, load-displacement and displacement-time curves for test and data display, saving, analysis and printing according

to need.

10. Curve pointwise traverse function: can click force and deformation value on the curve by mouse, to acquire parameters of each point.

11.Result contrast function: can observe various test curve at the same time, and can realize Characteristics contrast of specimen to be analyzed

by superposition and fractionated gain of various curves.

12. Force interface: force channel interface and test software can equip all kinds of sensors according to users’ need, and can conduct mark,

parameters modification and normal test.

13. Data sampling frequency: can select high-speed sampling frequency according to users’ test requirements.
