Bicycle Vertical And Horizontal Fatigue Testing Machine Bicycle Frame Horizontal Dynamic Fatigue Tester
Bicycle Frame Horizontal Dynamic Fatigue Tester
Application Of Bicycle Frame Horizontal 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.

Computer on-line function description.
1. Signal conversion controller.
(1) Load sensor
(2) Signal conversion collector
The basic function executes the saddle tube test program to obtain the following information.
(1) Real-time force vs. time curve
(2) Real-time frequency versus time curve
(3) Maximum value of tensile force
(4) Real-time values of fracture
(5) Comparison of graphs
(6) Standard deviation
