| Abstract: | In this paper,a finite element model of a frame is established.The modal analysis is made by Hyperworks,and then we get the natural frequency and vibration characteristic of the frame.Aiming at the minimum total mass,the size of the longitudinal beams and the traverse beams is optimized and a constraint of meeting the modal performances. |
