摘要
利用ABAQUS有限元软件,首先针对铝合金试件的淬火过程建立了数学模型,进行热传导分析,根据所求得的瞬态温度场修正该瞬时的材料弹塑性性质。在分析瞬态应力场时,导入已生成的温度场,从而实现准耦合模拟。在此基础上分析了板材内外部的温度变化情况及热应力分布情况。
A mathematical model of quenching process for 7075 aluminum model was simulated by ABAQUS-a powerful FEA,carrying out analysis of thermal conduction,according to analysis of transient temperature field to revise the elastic-plastic properties of materials.Read in the transient temperature field generated when analyzing the transient stress field,thus realize accurate coupling simulation.On the basis of the sheet internal temperature changes in the plate and the thermal stress distribution.
