用有限元分析软件ANSYS/LS-DYNA研究了6061Al/AZ31B/6061Al爆炸复合板的界面轧制变形行为。分析了复合板轧制方向和宽度方向的界面节点在不同轧辊转速和相对压下率下最大等效应力和应变的变化规律,并进行了定量比较。模拟结果表明:不同轧制条件下,镁铝复合板界面各节点的最大等效应变值和应力值呈现不同的分布特点。最大轧制力随相对压下率和轧辊转速而变化。在轧辊转速30 r/min、相对压下率20%时,可以获得较好质量的轧制复合板。结果能为镁铝爆炸复合板的轧制工艺提供理论参考。
The interfacial rolling deformation behavior of 6061Al / AZ31B / 6061Al explosive composite plate was studied by finite element analysis software ANSYS / LS-DYNA. The variation law of the maximum equivalent stress and strain under different roll speeds and relative reduction rates was analyzed and compared quantitatively. The simulation results show that under different rolling conditions, the maximum equivalent strain and stress values at the joints of Mg-Al composite plates exhibit different distribution characteristics. The maximum rolling force with the relative reduction rate and roller speed and change. In the roll speed 30 r / min, the relative reduction rate of 20%, you can get better quality rolled composite plate. The results can provide a theoretical reference for the rolling process of Mg-Al explosion composite plate.
