极薄、超宽规格装甲板压力淬火工艺数值模拟优化

利用数值模拟的方法对极薄、超宽规格装甲板淬火过程的畸变进行了模拟研究,并对脉冲式压力淬火的控制参数进行了优化。通过对比不同冷却条件装甲板的变形量,确定了脉冲式压力淬火的脉冲压力和周期。结果表明,脉冲约束的模拟条件下,装甲板在厚度Z方向上的最终变形量为1.7 mm,不仅小于2 mm的标准要求,而且可以实现装甲板的小淬火畸变前提下满足其表面无压痕、划痕等其他损伤的实际生产需求。

Numerical simulation and optimization of pressure quenching process of armor plate with specification of extremely thin and wide

Distortion of armor plate with the specification of extremely thin and wide in the process of quenching was studied by means of numerical simulation, and the parameters of pulse-pressure quenching were also optimized. Comparing the distortion amount of armor plate under different cooling conditions, the pulse-pressure and period were determined. The results show that under the simulation condition of pulse constraint, the final distortion amount of armor plate in the thickness direction Z is 1.7 mm, which is not only less than the normal requirements of 2 mm, but also can meet the actual production requirements of the armor plate surface without indentation, scratch and other damage under the premise of less quenching deformation.
