18MnNiMo钢核电厚壁锻件淬火冷却温度场数值模拟研究

摘要

Numerical simulation has been carried out for cooling process of forging with wall thickness 300 mm by finite element simulation software .By comparing with the measured cooling rate , the precision of numerical simulation has been optimized .%使用有限元模拟软件对300 mm壁厚锻件冷却过程进行数值模拟。通过与实测冷却速率对比，优化了数值模拟精度。
