In this paper, multi-input / multiple-output (MIMO) time-domain modal analysis theory is applied to the automotive engineering design, the experimental modal analysis and calculation of the automotive transaxle case (HFN24010 2 0 0 -0 7G) The finite element analysis software AN SYS was used to calculate the modal analysis of the axle shell, and the two were compared. The feasibility and superiority of applying MIMO time-domain modal analysis to dynamic analysis of automobile structure are analyzed
