In order to solve the optical dither problem of the inside rearview mirror of a certain vehicle, the finite element modeling and modal simulation analysis of the inside rearview mirror were carried out by using MSC NASTRAN software. Based on the results of the simulation analysis, the structure of the mirror rod and the base was optimized to improve the stiffness and modal, and the scheme was engineered and verified, which effectively solved the optical dithering problem of the rearview mirror.
