1. Overview of microcomputer controlled torsion testing machine
1. The NDW series microcomputer controlled torsion testing machine is composed of a loading system, a transmission system, a digital data acquisition and processing system and a computer measurement control display system. It is mainly used for metal materials (such as low carbon steel, cast iron, etc.), non-metallic materials Static torsion mechanical performance test of materials, replacement of test aids can also be used for static torsion mechanical performance test of various components such as drive shafts, half shafts, various wrenches, hardware tools, bolts and nuts, bimetal materials, and joints. This machine is mainly used for the torsion test of metal components. It adopts a horizontal structure, computer control and screen display, a digital data acquisition control system, and a full digital AC system. It has uniform loading, stable, no impact, and accurate data acquisition control. Features.
2. Test function: Windows7, 8 Chinese operating platform, realizing multiple controls of torque, torsion angle and deformation (special order). Using a window operating system with graphics as the interface, the display screen and operation panel can be set; the test speed and various control parameters can be set; the basic test results can be displayed in real time; various related curve graphics of the test process can be displayed in real time; Realize system diagnosis and display the diagnosis result. The testing machine realizes hierarchical management authority, and different users can enter different management interfaces, divided into three levels of user management authority.
3. The whole machine uses a fully digital AC control system and a digital data acquisition and processing system, a high-precision torque sensor detects the torque, and a photoelectric encoder collects the torsion angle of the sample.
2. Applicable standards of microcomputer controlled torsion testing machine:
1. JB/T9370—2007 "Technical Conditions for Torsion Testing Machines";
2. JJG269-2006 "Torsion Testing Machine";
3. GB10128-2007 "Metallic materials room temperature torsion test method";
4. The user can also provide relevant technical standards, and realize the control of the test method and related data collection and processing according to the standards provided by the user.
