| Abstract: | In the running of tracked vehicle, the road roughness is measured by acceleration sensors, photo electricity sensors, electric amplifier, and tape recorder. The recorded data was imported into Matlab by using import data of data analyzing and processing software, and the data was preprocessed to get the signal matrix. After filtering, rapid Fourier conversion, acceleration power spectrum calculation, roughness power spectrum calculation, the result can reflect the road characteristic. |
