This paper presents the static and dynamic behavior of car chassis using ANSYS. The application of static & dynamic technique together with Finite Element Tools had been utilized in order to verify the simulation and analysis of the chassis. Results were used in conjunction with the finite element to predict the dynamic characteristic of car chassis such as the natural frequency and corresponding mode shape. Damage can occur if the car chassis is excited at resonance during operation. Therefore, based on the result gained from the finite element analysis, further enhancement of the current chassis had been done through the chassis FE model in order to improve its stiffness as well as reduce the vibration level. In Finite Element Analysis, the model of car chassis was created using 10 nodes tetrahedral elements. Normal mode analysis was performed and free-free boundary condition was applied in the analysis to determine the first seven natural frequencies and mode shapes. It was noticed that the first seven natural frequencies of the car chassis were below 100 Hz and vary from 47.423 to 79.531 Hz. This problem was resolved by carrying out the Finite Element Model updating, by adding sub-structure.
