数值模拟技术在保证工件质量、减少材料消耗、提高生产效率、缩短试制周期等方面显示出无可比拟的优越性。在钢锭凝固方面,有限元模拟程序MIPS可以分析凝固过程中温度场的分布,确定不同时刻凝固前沿的位置,而且能预测缩孔和疏松的位置及尺寸。使用该程序对220吨钢锭的生产工艺进行优化,成功地解决了疏松进入锭身的问题。在锻造方面,已开发出了基于ANSYS的三维大变形弹塑性、弹粘塑性程序,可以分析复杂的三维金属塑性成形问题。热处理专用软件NSHT不仅可以分析加热、淬火及回火过程中温度场分布,而且可以给出应力的分布及相态的变化过程,并已在实际生产中取得了成功。
Numerical simulation technology in ensuring the quality of the workpiece, reducing material consumption, increase production efficiency, shorten the trial cycle and so show unparalleled superiority. In solidification of ingot, the finite element simulation program MIPS can analyze the distribution of temperature field during solidification, determine the position of solidification front at different time, and can predict the location and size of shrinkage cavity and loosening. Using this program to optimize the production process of 220 tons ingot successfully solved the problem of loosening into the ingot. In forging, has developed a three-dimensional large deformation based on ANSYS elastoplastic, visco-elastic plastic program, you can analyze the complex three-dimensional metal plastic forming problems. NSHT, a special software for heat treatment, can not only analyze the distribution of temperature field during heating, quenching and tempering, but also give the distribution of stress and the change of phase state, and has achieved success in actual production.
