摘要：

为了提高超级马氏体不锈钢04Cr13Ni5Mo转轮锻造仿真温度场、载荷场的预测精度，提出了一种锻造仿真热力学参数的稳健设计方法。分析了建模基本参数对仿真结果偏差的影响，确定坯料-环境换热系数h1、坯料-模具换热系数h2为主要影响因素，并利用有限元软件Forge建立仿真模型，结合39 t转轮实测数据，对h1和h2进行优化反求，得到有利于提高热力学参数稳健性的建模参数组合。比对发现，h1和h2值优化后，仿真温度场偏差率由9.9%降低至3.6%，最大载荷偏差率由14.6%降低至4.8%。对54 t转轮的镦粗、局部（渐进）镦粗、冲孔3个工序进行仿真，并与实际生产情况对比，各工序仿真温度场偏差率在±4%以内，最大载荷偏差率在±7%以内，表明该锻造仿真热力学参数的稳健设计方法具有较高的可靠性。

In order to improve the prediction accuracy of temperature field and load field in the forging simulation of super martensitic stainless steel 04Cr13Ni5Mo rotary wheel, a robust design method for thermodynamic parameters of forging simulation was proposed. The influences of basic modeling parameters on the deviation of simulation results were analyzed, and billet-environment heat transfer coefficient h1 and billet-mold heat transfer coefficient h2 were determined as the main influencing factors. Then, the simulation model was established by using the finite element software Forge, and h1 and h2 were optimized and reverse calculated combining with the measured data of the 39 t rotary wheel. The modeling parameter combination improving the robustness of thermodynamic parameters were proposed. It was discovered that the deviation rate of simulated temperature field decreased from 9.9% to 3.6%, and the maximum load deviation rate decreased from 14.6% to 4.8% after optimizing the values of h1 and h2 by comparison. Finally, the three processes of upsetting, local (progressive) upsetting and punching for the 54 t rotary wheel were simulated. The results show that the deviation rate of the simulation temperature field and the maximum load deviation rate for each process are less than ±4% and ±7%, respectively compared with the actual situation, indicating that the robust design method for the forging simulation thermodynamic parameters has high reliability.
