| Abstract: | Taking a car body of one development project as an example,this paper makes modal analysis of the simulation analysis model using the software of ANSYS,and gets the natural frequency and vibration mode of the local part of car body.Based on the modal analysis,it makes harmonic response analysis of two kinds of installation scheme for transformer,and gets the structure response under different frequency force. |
