First, product introduction
WDW-D series electronic universal testing machine is a single arm type structure, adopting AC servo motor as power source, arc belt reducer, ball screw loading. Using high precision load sensor, photoelectric encoder and electronic extensometer respectively to test force, displacement and deformation were measured by electronic universal machine dedicated controller can loop control of the three parameters, and can realize smooth switching between the three kinds of control mode, has high control accuracy, strong adaptability, good long-term stability and other characteristics. The machine can be used to test and analysis of mechanical properties of various metals and non metals and composite materials, widely used in aerospace, petrochemical, machinery manufacturing, electric wire, cable, fiber, textile, plastic, rubber, ceramics, food, pharmaceutical packaging, plastic pipe, plastic doors and windows, geotextile, film, wood, paper, metal materials and manufacturing, electronic tensile testing machine according to GB, JIS, ASTM, DIN, ISO and other standards automatically calculate the maximum test force, fracture stress, yield strength, yield strength, tensile strength, compressive strength, elongation, tensile modulus, flexural modulus of elasticity test data.
Two, to meet the test standards
The electronic universal testing machine software package built-in "GB/T228.1-2010 tensile test method", "GB/T 528-2009 rubber vulcanized or thermoplastic Determination of tensile stress-strain properties", "GB/T1040-2008", the determination of tensile properties of plastics "GB/T1041-2008 plastic compression performance test" more than and 30 standard test, can also be added to modify the software according to the user's requirements, meet the requirements of various special tests.
Three, functional characteristics
1) the controller uses high speed ARM chip as the main control chip, has high operation speed and the ability of data processing, can realize the whole control process from data acquisition, PID and Ethernet communication operation to the output control in a short period of time, in order to achieve accurate closed-loop control of testing machine;
2) input channel:
A, with three analog input channels: 1 load, 1 road, 1 Road extension electronic extensometer channel, the three channel 24 bit A/D converter used in all independent high-precision data sampling, effective code up to 400000;
B, up to 15 segments of the linear compensation and correction function, greatly improve the sensor's measurement range and measurement accuracy;
3) control function:
A, using PID control strategy to achieve the closed-loop control of the load, to achieve a constant speed and load, load to maintain the function;
B, using PID control strategy to achieve closed-loop control of displacement, to achieve a constant speed displacement, displacement and other functions to maintain;
C, using PID control strategy to achieve closed-loop control of deformation, to achieve constant speed deformation, deformation and other functions to maintain;
4) communication interface:
Within the 100MHz Ethernet communication interface, and PC to achieve high-speed data communications, real-time data acquisition and control of real-time data upload instructions issued by the function, so as to achieve the purpose of real-time control of the PC machine.
2, measurement and control software features:
1) measurement and control software with a new software style, with the interface beautiful and generous, powerful, easy to operate and so on;
2) can configure any number indication display box, display unit, channel, the decimal point can be configured, and you can choose to display the box horizontally or vertically;
3) test curve frame number from 1 to 3 can be arbitrarily selected, and the layout of multiple curve frame can switch curve coordinates frame can be arbitrarily selected, the test curve can be magnified, and can be saved as image files;
4) can be configured with a number of force sensors and multiple sensors, the user can switch to use;
Three) has 5 levels of management authority, respectively is the factory debugging member, the manager, the test member;
6) using standard test open configuration mode, standard software with built-in GB/T228.1-2010, GB/T1040-2008, GB/T528-1998 and other more than and 30 test standard, users can easily add, delete or modify a standard test according to test requirements, control step free editing;
7) can automatically calculate and save the test result data, such as maximum force, tensile strength, yield strength, non proportional extension strength and so on, and can display the characteristic points on the test curve;
8) software has the function of test and analysis, it can analyze the data of the test results that have been completed, and can be compared to a set of multiple test curves;
9) using standard database to manage the test data, and can provide network data interface;
10) users can choose my company's independent development of the SingoReport reporting system to edit and print reports, you can also use EXCEL form to edit and print statements;
3, safety protection
1) when the servo motor over current, over voltage and over speed, the servo motor controller will alarm and stop;
2) limit protection: when the moving beam touches the upper and lower position, the moving beam automatically stops moving;
3) automatic stop: after the specimen breaks, the moving beam stops moving automatically;
4) overload protection: when the load exceeds the maximum value of 3-5%, the moving beam automatically stops moving.
