Data Acquisition Systems: National Instruments 19. The load point shift measurement accuracy: ± 2.5% 20. Load arm: 760mm (measured from the wheel mounting surface) 21 sampling points: 3000 22. Weekly displacement measurement: Japanese precision sensor 23. Host Dimension: 1.25m × 1.25m × 1.25m 24. Weight: 2t about four, device descriptions and functions: 1. Host by the new high-quality steel components: 2. Control: Computer Control 3. The computer automatically displays: moment, speed, number of rotations, offset operating hours, bend - the number of revolutions (or time) curve element analysis and stress test conditions and status, moment - rotation (or time) curve should keep complete records, and can print complete test report or by EXECL output; 4. Monitoring methods: color LCD screen and printer; 5. Measurement control functions performed by the computer, the computer DELL brand / LCD / HP Color Inkjet Printer / windows XP / systems; 6. system interface using good man-machine interface, input, display the following parameters; 1) The moment setpoint / moment found 2) arm offset the initial value, partial arm shift instantaneous value, limited arm offset incremental value (as downtime Provisions) number 3) Test speed 4) load change 5) Wheel size 6) user wishes to input 9. other content have security features and facilities, security automatic protection system can not be started when the door is opened and the alarm device 10. The number of revolutions can be set to automatically shut down and unloaded reaches a predetermined number of revolutions; 11 to set the load point displacement control values ??when loading point to reach the initial value of the offset 120% of the time, or other value, the device automatically unloading stop, and stop the test shows the reason; 12. control system with zero-voltage-safe function, ie a sudden power failure or other reasons make the program running is interrupted, all data will be is stored, the program stops running and unloading, after a reboot without re-entering, the test may be continued; five computer PC: The next memory front side bus speed of 400MHz: brand machine, the following configuration Processor: C331 2.66G 64-bit memory memory running at 266MHz Hard: 320G 7200 switch Memory: 64MB dynamically allocated to support the largest memory Display: 19-inch LCD Optical drive: DVD card: Integrated 10 / 100M LAN keyboard: waterproof antibacterial keyboard and mouse: Optical Mouse theft antibacterial software: Operating System (OPERATING SYSTEM): WINDOWS latest special wheel torque under special test software, the software itself is attached with detailed instructions, and supplied a detailed set of operating instructions. Computer is compatible with OS / 2, NOVELL, UNIX, WINDOWS NT and other network and multi-user operating system for a variety of software packages PC compatible machine's list: the list of machines using HP color can automatically print a maximum break point and other functions Six control software has the following main functions: 1) Automatic American NI high-speed data acquisition, the sampling rate is more than 2MHz; 2) the United States NI automated data processing systems; 3) automatically saves all test data, and can automatically retrieve data automatically test reports, automatically selected according to the needs of print 4) full closed-loop control system computer automatically Moment 5) Test curve selectable: bending moment and displacement curves, moment and time curve, displacement and time curve 6) speed automatic or manual adjustments 7) counting the number of load changes (stopping off keeping count) 8) Load preset maximum displacement limit value monitoring arm 9) shutdown condition monitoring (shutdown reasons displayed) 10) fault monitoring (fault prompt content display) VII equipment list: Host A computers (including the host and display) a printer a control cabinet a description of a certificate of a warranty card Eight, equipment for energy and environmental requirements: 1.
