By means of the finite element analysis theory and taking an electric vehicle frame as research object ,the finite element model of the frame was established by the software HyperWorks . The stress-strain contours of the frame were obtained by the static analysis under the fully loaded bending and torsion conditions ,and the first ten orders of inherent frequency and main vibration mode were obtained by the modal analysis .Through analyzing and predicting the weak parts of the frame ,the improved scheme and some suggestions were proposed ,which provided a reference for the structural optimization design of the electric vehicle frame .
