In this paper, Pro / E software to establish a shaker beam model, based on the finite element modal analysis to be much larger than the natural frequency of the lower beam of the working speed of the shaker, which can effectively avoid the resonance region. To achieve a solid modeling and finite element analysis and calculation of the seamless integration, improve the efficiency of finite element analysis. The use of Pro / M under the beams of the modal analysis, identify problems, to eliminate hidden perils, saving investment, but also shorten the product development cycle. From ANSYS and Pro / E comparison of results of the analysis, we found that Pro / MECHANICA modal finite element calculation results with sufficient accuracy. For other parts of this design provides a new approach.
