Abstract：Basic theory of ANSYS program and the property of SOLID186 structural units are introduced, and the relative parameter of coupled vibration is defined through ANSYS finite element program.The structure model of the main drive system and the strip for a rolling mill is built according to actual blueprint, and modal analyzed.The natural frequencies of the model and its mode shape are obtained, and carried out harmonic response analysis.Finally, the results proved that system structure begin resonance when the harmonic load frequency of the model is 8.4Hz, the model of the main drive system and the strip.And the results are referenced for the design and production of other similar rolling mills.
