摘　　要：针对精密铸造数值模拟中存在工艺参数操作繁琐、仿真效率低、系统性总结匮乏的问题,构建了基于浇注面定位技术和自动化仿真流程技术的高温合金精密铸造工艺快速仿真平台。该平台集成了从CAD设计到CAE仿真的过程,融合了浇注系统参数化、铸造工艺参数设计、仿真结果动态显示和仿真报告下载等功能,建立了10类仿真模版和237套模型库,实现了自动化快速仿真。以某动力涡轮机匣为例,利用该平台构建仿真模型、参数设计变量和结果预测优化指标进行仿真计算。模拟结果与实际生产一致,仿真效率大幅提高。In response to the challenges of complex parameter operations,low simulation efficiency,and lack of sys⁃tematic summaries in investment casting numerical simulations,a rapid simulation platform of investment casting pro⁃cess for superalloy was established based on pouring surface positioning and automated simulation process technology.The platform integrates the process from CAD design to CAE simulation,integrating functions such as parameteriza⁃tion of gating system,design of casting process parameters,dynamic display of simulation results,and download of simulation reports.Ten types of simulation templates and 237 sets of model libraries were constructed,achiving auto⁃mated rapid simulations.Taking a certain power turbine casing as instance,simulation model,parameter design vari⁃able and optimized prediction criteria were built up in the platform.The simulated prediction results are consistent with actual production defects,and simulation efficiency is significantly improved.
