3. Product functions:
1. The testing machine is mainly composed of a host, parameter measurement display unit, strong current control unit, test with centrifugal force measurement system.
2. The main machine is made of casting structure, the sample is easy to install, the wheel does not rotate, the load rotates
3. The applied torque measured by the relationship between load and speed can greatly save the test energy consumption.
4. The driving power adopts variable frequency speed regulating motor to achieve stepless speed regulating, which drives the load to rotate at high speed and exerts the bending moment on the wheel of the rotating shaft.
5. The test detects the bending of the spindle during the test, so as to achieve the emergency stop function of the wheel damage.
6 Centrifugal force sensor as a force acquisition source, high-speed acquisition, multi-channel division.
7. The measurement control software has the following main functions;
1) Test parameters are set by software;
2) The software displays test graphics, loading force values, etc
3) Report printing; Document management; Load calibration;
Detailed description is as follows:
1. Moment closed-loop adjustment
2. The bending moment and displacement resonance circle are displayed on the X-y coordinate system of the screen
3. Speed adjustment, load change number count (stop and shut down count keep) test parameters stop and shut down keep
4. The preset loading arm maximum displacement limit value monitoring, can input/display the following parameters; Bending moment set value/bending moment measured value
5. The initial offset of the lever, the instantaneous value of the offset of the lever, the limited value of the offset increment of the lever (as the shutdown regulation), and the test speed
6. With safety protection functions and facilities, safety protection door can not be tested when opened, the test has a safety alarm prompt function; The number of revolutions can be set, and the machine will stop automatically when the specified number of revolutions is reached;
7. Configure the strong current control box to complete the drive control of the motor.
8. Microcomputer control unit, industrial control computer, computer built-in signal amplification A/D conversion integrated board, to complete the sensor signal amplification and signal analog-to-digital conversion,
9. The computer software for WINDOWS platform software, with dynamic display, storage, output test report and other functions.
10. Other electrical components are all imported international well-known brands.
