Problems solved by technology
[0002] my country is a big country of bicycle production. While people pay attention to the beauty of bicycles, they also pay more and more attention to the quality of bicycles. Because it directly involves safety issues, many bicycle manufacturers do not test the parts of bicycles at present, so there will be many safety hazards
Recently, equipment for testing bicycles has appeared on the market. For example, the application number CN200520027175.8 provides an intelligent testing equipment for fatigue experiments on bicycle components under complex working conditions. Its characteristics are: it is mainly composed of a base and a column Fixtures for fixing the bicycle components under test are installed on the bracket, and a computer-controlled drive cylinder is installed on the bracket. The piston rod of the drive cylinder is equipped with a connecting rod with a tension and pressure sensor connected to the computer, and the other end of the connecting rod is hinged. The force point of the measuring department solves the problem of lack of accurate fatigue test for bicycle parts and improves the means of testing bicycle quality
However, this test equipment has limited test functions and a low degree of automation.
