Abstract: The finite element analysis software ANSYS was used to propose a parametric model and analysis for four corners tower of feed tank. Considering the multiform work condition load of internal pressure, liquid static pressure, wind load and seismic load, implement optimum was designed for structure of flat head. According to moment of flexion about bearing ring flatplate, the size and quantities for foundation bolt were counted. The strength calculation of the whole equipment was completed, which laid a foundation for further detailed design and manufacture. The results show that production was of certain guiding meaning for the four corners tower engineering design.

Key words: Four corners tower, Wind load, Seismic load, Modal analysis, Finite element analysis
