Finite Element Analysis of Model SZX20×2 Low Temperature Twin-Screw Oil Press

Worm is the executive component of the twin-screw oil press, and the design of the worm effect the performance of twin-screw oil press. In this paper the 3-dimensioned geometric model of the worm was established with SolidEdge, the static analysis for the established model was finished and the natural frequency of the worm was analyzed with ANSYS Workbench. Then the first six level natural frequencies and vibration mode were obtained, which provide the basis for dynamic analysis of the worm.
