Electric bicycle frame front fork vibration testing machine

1、 Scope of application:

It can dynamically simulate and load the frame/fork assembly of electric bicycles to achieve the testing process of vibration of the frame/fork assembly. This equipment is mainly used to test the strength performance of the frame/front fork assembly, and is suitable for conducting front and rear vibration tests on electric bicycle frames.

2、 Experimental principle:

The test sample will be fixed on the testing platform according to the standard test requirements, fully simulating the force situation of an electric bicycle during riding. The size of the test force and the number of vibrations will be set according to the standard. After a certain number of tests, observe whether the frame breaks or cracks, and whether the connectors and fasteners are loose. If the test piece is damaged halfway or the number of test times reaches, the machine will automatically stop and retain the test results.

3、 Meet the standards:

GB17761-2018Safety Technical Specification for Electric Bicycles;

GB 3565-2005Bicycle Safety Requirements;

DIN 79100-2000Bicycle Safety Requirements and Test Methods;

QB/T1880-2008Bicycle Frame;
