| Abstract: | Lab-scale simulation methods of road vibration signal of body parts were discussed, taking the rearview mirror of a certain car as an example.The outdoor signal spectrum of rearview mirror was gathered, processed and analyzed to obtain its characterization parameters and characteristics.Based on the energy equivalent principle and the random vibration test equivalent conditions, the equivalent relationship was obtained by comparison of outdoor vibration test results with indoor vibration test standards. |

| Keywords: | automobile rearview mirror signal spectrum vibration test equivalent relationship |
