| Abstract: | In this paper, the finite element software is used to simulate the structure of the hollow extruded aluminum profile under finite conditions to explore its vibration and noise reduction characteristics.In order to explore the vibration and noise reduction characteristics of aluminum vehicle body structure, based on CAD/CAE software platform, the finite element software ANSYS is used to model the body section.Ignoring some influencing factors, the finite element method is used to analyze and study the structure of aluminum profile car body, calculate the natural frequency of the profile structure and obtain the modal mode diagram, and analyze and predict the vibration characteristics of the structure of different profiles. |

| Keywords: | aluminum profile finite element method natural frequency modal vibration mode |
