| Abstract: | The paper is about the typical failure mode of vehicle transmission oil line. Vibration characteristics has been obtained through vehicle road test. And through Fourier transform,PSD frequency spectrum has been obtained, based on that the input data of test bench has been modified. The test results indicate that failure mode of transmission oil line can be simulated well. |
