Fatigue Life Analysis of Large-Scale Liner Vibration Screener Based on ANSYS

Based on the theory of fatigue life prediction and by using the local stress-strain method and the material S-N curve of Q235 deduced by empirical formula; the fatigue was analyzed for the key parts of large-scale liner vibration screener by means of the general finite element analysis software, ANSYS. Thereby, the working conditions of force bearing, reliability and fatigue life-span of the key parts can be judged. The study will provide a theoretical basis for the design , manufacture, and installation of the large-scale liner vibration screener.
