ISO 4210 Bicycle Frame Vertical Dynamic Fatigue Tester
Bicycle Frame Vertical Dynamic Fatigue Tester
Application Of Bicycle Frame Vertical Dynamic Fatigue Tester
This machine for bicycle frames to do fatigue testing. It can test
bicycle frame pedaling fatigue test EN 15194 electric bicycle,
ISO4210-6.4.4 all styles of frame of this test specification.
Test principles
According to the standard: EN 15194 electric bicycle, ISO4210,
EN14781 roadster, EN14766 mountain bike, EN14764 city car. designed
by CNS, JIS, DIN, NF, ISO, CPSC, CSA, AS, BS nine countries testing
standards.
Test method
1 Fix the frame on the test machine according to the standard
method, and the position of the fork can be adjusted manually to
fit the size of the frame.
2 Fix the car driver and fork on the roller axle, and fix the rear
hook on the rear axle, and lock the rear axle fixing block.
3 Attach the frame vertical force loading fixture assembly to the
test machine in accordance with the standard method, the height of
the loading beam can be adjusted manually to suit the height of the
frame.
4.Set the test force value and number of times required for the
test on the computer.
5.Adjust the maximum deformation of the frame allowed, the machine
will automatically stop the test after exceeding some deformation.
6.Start the test program to start the test, the test reaches the
set number of times or test piece damage, automatically stop the
test and retain the test results.
