PC Controlled Handlebar Dynamic Fatigue Testing Machine (ISO standard)

PC controlled Handlebar Dynamic fatigue testing machine (ISO standard)WSD-8714

First, the test principle: simulate the bicycle in the actual riding process, under different road conditions, the handlebar component will be given by the hand in different directions of the force, especially when riding on the bumpy road, the force is relatively large and frequent, so the quality of the handlebar component is related to the safety and convenience of the whole car. The testing machine is designed according to ISO 4210-5-2014 related fatigue test standards. The whole test system is automatically controlled by computer, and the force application system adopts force closed-loop control. When the test force applied on the handlebars reaches the set force, it automatically returns and reverses.

2, according to the standard: ISO 4210-5-2014 4.9 first and second stage loading mode, ISO 8098-2014

Iii. Test method:

1) During the test, the handlebar assembly is fixed on the test machine in accordance with the standard method, and the height of the loading beam can be manually adjusted to adapt to the size of the handlebar riser;

2) Fix the handlebar riser (or false riser) on the special fixture, adjust the upper and lower, left and right positions of the loading cylinder, so that the loading fixture can be just assembled on the horizontal pipe, and fix all parts.

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

4) Adjust the maximum deformation of the handlebars, 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.

1. Sensor capacity: 5000N

2. Load element resolution: 1/10,000

3. Test force: 100N-600N can be set

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

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

6. Equipped with non-contact displacement sensor to measure the deformation of the handlebar during the test

7. Test times: 0-999,999 times can be set

8. Loading mode: pneumatic loading

9. Database function: automatically record each measurement result to facilitate analysis and provide evidence

10. Equipped with fixtures: 90° fixtures, 70° fixtures, racing fixtures

11. Stop mode: The test piece breaks the system or automatically stops beyond the displacement

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

13. Pneumatic components brand: Japan SMC or Germany FESTO

14. Equipped with SMC proportional pressure regulator, automatically adjust the air pressure of the cylinder.

15. Power supply: 220V 5A

16. Air source: Pressure 0.7MPa gas flow 300L/MIN

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

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

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