Equipment usage:

The tire rolling resistance testing machine is a mechanical device used to dynamically measure the tire rolling resistance. It consists of a simulated road surface (annular steel belt or drum), a cantilever frame, a side inspection system, and an electronic computer. The annular steel belt or drum is driven by an electric motor to rotate according to the required test speed. During the test, the tire is first fixed to the axle of the cantilever frame, and the supporting part of the axle is equipped with a force sensor to make the tire come into contact with the simulated road surface, Add load to the tire_ f. When the simulated road surface drives the tire to rotate, a signal is sent out by the detector and input to an electronic computer for data processing and analysis, which can output the tire rolling resistance value.
