摘要：A three dimensional thermo-mechanical finite element model of rolling for wide and heavy plate was developed by using the FE software MSC.MARC.The width spread results obtained by this model were compared with the measured ones under the same condition and the feasibility of the FE model was verified.The rolling processes of four typical dimension plates were simulated, the distribution of friction coefficient and friction force at the contact area,the edge shape and average width spread with different friction coefficients were obtained.The simulation results show that the width spread on surface decreases and the width spread on symmetry plane in height direction increases with the increasing friction coefficient.The average width spread decreases with the increase of friction coefficient.The decreased trend of average width spread is more obvious with the decrease of the width of plate and with the increase of reduction.Based on the data obtained from the simulation,a modified Shibahara's spread formula considering friction coefficient is obtained and the calculated results of the formula agree well with the simulated ones.
