Full-automatic hydraulic press is widely used in ceramic industry for pressing the adobe of all kinds of specific ceramic tiles, so it is also referred to as ceramic press. The upper beam is one of the most critical stressed members of the ceramic press. The paper took 21MN ceramic press as the research object, completed the finite element static analysis of its upper beam. First established the three-dimensional model of the beam by CAD software Pro/ENGINEER, and then imported the model into CAE software ANSYS and analyzed the stress and strain distribution in detail. The results can provide some useful reference for ceramic press design and optimization.
