NDW series Computer Control Torsion Materials Testing Machine - NDW series

NDW series Computer Control Torsion Materials Testing Machine

Main Applications:

This testing machine uses Computer-controlled AC servo system and is loaded through the active clamping head driven by the AC servo motor and cycloidal pinwheel redution motor. The torque and torsion angle are measured with high-precision torque transducer and photoelectric encoder. Computer will dynamically display the test torsion curve ,loading speed, peak value, and so on.It is mainly used for the torsion test of metal and non-metal materials, as well as the torsion test for parts and components.

It is an essential instrument to measure torsion properties of materials for mechanics laboratories of aviation industry,construction industry, scientific research dept., universities or industrial enterprises.

Main Functions and Features:

Loading mode: use imported AC servo motor and driver;

Testing of torque and torsion angle: high-precision symmetrical torque transducer for torque testing and high-precision LEC model photoelectric encoder for angle testing;

Operation: manual control and computer control;

use WINDOWS-based supervision software to calculate mechanical indexes of materials. Auto process test data, dynamically display testing curve, store and print the testing results. Operator can intervene in the analysis process and thus improve the analyzing accuracy.

Software introduction:

· Microsoft Windows operation platform, screen display, mouse action

· The test torque and peak value display from 4 to 6 measuring ranges, torsion angle display in four measuring ranges, automatic calibration.

· Recording torque- torsional angle, torque-time, torsional angle-time & corner-time trend simultaneously, and can switching over for observation at runtime.

· Data is processed in man-machine interaction mode, meets the requirements of the standard “ Torsion Test Method Of Metallic Materials Under room Temperature”. Data processing can be realized automatically, also interfered in manual mode to boost the accuracy.

· Test data stored by the form of ASCII code into “.txt” file, so convenient for customers to reprocess test data utilizing any form of commercial statements and word processing software, printing test reports as the format customer request.

· System supporting Open Loop control mode and Entire Close Loop (as Torque, Torsional Angle and Encoder Angle) control represents the high control level of testing machine.

· System provides customer with secondary programming function which means control more easy, process more flexible, adapts to many actual testing requirement.

· System support any commercial printers, customer can customize printing contents himself.

· Factory parameters is stored into files, easy to restore.

· Simple and reliable upgrade of system
