PLC Controlled Bicycle Frame Vertical Force Fatigue Testing Machine (iso)

PLC control frame vertical force dynamic fatigue testing machine (ISO standard) WDSD-8701A

First, the test principle: During the actual riding of the simulated bicycle, under different road conditions, because the rider's own weight will produce a certain pressure on the saddle, it will be transmitted to the frame through the saddle tube, especially when riding on the bumpy road, the force on the frame is relatively large and frequent, so the quality of the frame is related to the safety and convenience of the whole car. The testing machine is designed according to ISO4210-6:2014 4.5 related fatigue test standards. The whole test system is automatically controlled by computer. The force application system adopts force closed-loop control, and automatically returns when the test force applied on the frame reaches the set force.

2, according to the standard: ISO4210-6:2014 4.5

Iii. Test method:

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

2) Fix the frame and false front fork on the roller axle, and fix the rear hook claw on the rear axle, and lock the rear axle fixing block.

3) During the test, the vertical force loading fixture assembly of the frame is fixed on the test machine in accordance with the standard method, and the height of the loading beam can be adjusted manually to adapt to the height of the frame;

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

Four, the main technical parameters:

1. Sensor capacity: 5000N

2. Load element resolution: 1/10,000

3. Test force: 600N-1500N can be set

4. Test frequency: 0-3Hz (adjustable)

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

6. Loading mode: pneumatic loading

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

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

9. Pneumatic components brand: Airtek

10. During the test, it can be displayed on the touch screen: set the actual force value

Set Times Actual times

11. Power supply: 220V 5A

12. Air source: Pressure 0.7MPa gas flow 150L/MIN

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

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

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