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

PC controlled frame foot force fatigue testing machine (ISO standard)WSD-8702

A test principle: In the actual riding process of a 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.

two. According to standard: EN 14764:2005 4.8.3

EN 14766:2005 4.8.4

EN 14781:2005 4.8.4

Three test methods:

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.

Four... Technical parameters:

9) Cylinder loading Angle: 0-10° adjustable

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

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

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

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

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

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

16) 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.

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

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

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

20) Pneumatic components brand: Germany FESTO

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

22) Equipped with independent electric control box,

23) Software update, can not have the phenomenon of stuck in operation.

24) Paint the surface to protect.

25) The rear axle is made of quick-change type.

26) Power supply: 220V 5A

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

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

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

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