PLC controlled frame foot force fatigue testing machine (ISO standard)

PLC control frame foot force fatigue testing machine (ISO standard) WDSD-8702A

First, the test principle: In the actual riding process of the simulated bicycle, the rider will constantly step down the pedal, and the trampled force will be transmitted to the five passes of the frame through the crank and five-pass shaft assembly, and the five passes of the frame will constantly bear the external force. The quality of the five pipes is related to the safety and convenience of the entire car. The testing machine is designed according to ISO4210 EN14764, EN14766 and EN14781 frame foot force fatigue test standards, the entire test system through the computer automatic control, the force application system adopts force closed-loop control, when the test force applied to the frame reaches the set force automatically return.

2, according to the standard: ISO4210

Iii. Test method:

1) During the test, the frame is fixed on the test machine in accordance with the method specified in the standard, and the position of the false front and rear axles can be manually adjusted to adapt to the size of the frame;

2) Adjust the height of the false front axle and false rear axle to meet the standard requirements and the same as the actual car;

3) Adjust the Angle and height position of the left and right foot loading cylinder to meet the standard requirements.

4) Fix an adjustable part to prevent loosening during the test and affect the test.

5) Set the test force value and number of test requirements on the computer.

6) Adjust the maximum allowable deformation of the frame, and the machine will automatically stop testing after exceeding this deformation;

7) Start the test procedure to start the test, the test reaches the set number or the specimen is damaged, the machine will automatically stop the test and retain the test results.

4. Technical parameters:

1) Applicable frame size specifications: 16 "-29"

2) Sensor capacity: 5000N

3) Load element resolution: 1/10000

4) Test force: 600N-1200N configurable (force closed loop control)

5) Force control accuracy: 0-5% (dynamic)

6) Test frequency: 0-5Hz (adjustable)

7) Cylinder loading Angle: 0-10° adjustable

8) Test times: 0-999,999 times can be set, automatically retain the test results

9) Loading mode: pneumatic loading, the loading mode is drop-down

10) Database function: automatically record each measurement result to facilitate analysis and provide evidence

11) Shutdown mode: The test piece breaks the system or automatically stops beyond the displacement

12) Equipped with special test five-way fixture, with rolling bearing installation, can freely rotate, will not shake

13) With rigid front fork (double rod type). During the test, it is fitted with the first bowl group.

14) The height of the front and rear fixed seat can be adjusted, and the front fixed shaft will not shake during the test. Rolling bearing size increase.

15) Adjust the position of the locking screw selection of quick disassembly, easy to operate, adjust the position using the lead screw adjustment.

16) The solenoid valve is equipped with a guard to prevent damage.

17) With pressure regulating tank, better stable working pressure, so that the loading force is more stable.

18) Pneumatic components brand: Airtek

19) Shutdown conditions: low gas supply pressure, large deformation of the frame, and the stroke of the cylinder exceeding the set value

20) Equipped with independent electric control box

21) Power supply: 220V 5A

22) Air source: pressure 0.7MPa gas flow 400L/MIN

23) The main body of the machine is a steel component, high strength, not easy to deformation.

24) The base of the machine is solid steel, with good stability, equipped with reinforcing bars and water transfer feet.

25) Electrostatic spraying of machine appearance, electroplating of other parts, high rust prevention ability, beautiful appearance.
