| Abstract: | In this paper, the 3-D model of engine cranckshaft by using solidworks is built and an FEA of cranckshaft by using CAE software is made. At the same time, the detailed features and constrains on the cranckshaft are simplified by means of Lanczos method. The Lanczos method is also used in the modal analysis in order to abtain the natural frequences and the vibration-mode vectors of the first 50 orders. |
