摘要：
The natural frequencies and modes of a structure can be determined by the modal analysis. In this paper, the CATIA software based on the FSC car frame to carry out a three-dimensional modeling, save as STP format. In the Workbench ANSYS, the modal of the frame is solved by the finite element method, and the first 10 order non zero modes and the natural frequency of the frame are obtained. The natural frequency is calculated when the engine idle speed is 33.3Hz, the normal speed frequency range of 5000-7000r/min is 166.7-233.3Hz, the natural frequency of the finite element method to calculate the first 10 order vibration mode under 100Hz, so the conclusion of this paper is the frame model of the scheme effectively avoids the excitation frequency of the engine and to avoid the risk of resonance.
