PC controlled Bicycle frame front fork fatigue Testing machine (ISO standard)

Pc-controlled front fork fatigue testing machine (ISO standard) WD-8704

First, the test principle: In the actual riding process of the simulated bicycle, the wheel will be affected by the external force forward and backward, so that the front fork will continue to bear the alternating external force. The quality of the front fork is related to the safety and convenience of the whole car. The testing machine is designed according to ISO fatigue test standards, the whole test system is automatically controlled by computer, the force application system adopts force closed-loop control, when the test force applied on the frame reaches the set force, the automatic return and reversal.

2, according to the standard: ISO 4210

Iii. Test method:

1) During the test, the front fork assembly is fixed on the test machine in accordance with the standard method, and the height position of the front fork can be manually adjusted to adapt to the position of the loading cylinder;

2) Fix the front fork assembly on the special fixture, adjust the left and right position of the loading cylinder, so that the loading fixture can be just assembled on the front fork, and fix all parts.

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

4) Adjust the maximum allowable deformation of the front fork, and the machine will automatically stop the test after exceeding this deformation;

5) 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.

Four, the main technical parameters:

1) Sensor capacity: 5000N

2) Load element resolution: 1/10000

3) Test force: 300N-1000N configurable (force closed loop control)

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

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

6) Number of tests: 0-999,999 times can be set

7) Loading mode: pneumatic loading

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

9) During the test, with the first bowl set of the car to be installed with fixtures: front fork horizontal fatigue test

Lateral fatigue test

20° tilt Angle fatigue test

Disc brake front fork fatigue test

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

11) Shutdown conditions: low gas supply pressure stop, large deformation of the specimen, and the stroke of the cylinder exceeds the set value

12) Equipped with independent electric control box,

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

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

15) Pneumatic components brand: Japan SMC or Germany FESTO

16) Power supply: 220V 5A

17) Air source: pressure 0.7MPa gas flow 200L/MIN

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

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

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