基于AnyCasting的阀门阀盖铸造工艺模拟 摘要：随着计算机技术和数值计算技术的发展完善，计算机在铸造领域得到了广泛的研究和应用。它可以在不进行实际浇注的情况下，模拟铸造的充型、凝固、传热、应力场、微观组织分布、缩孔及缩松的形成等过程，可以大大提高生产效率和经济效益，对于铸造生产具有十分重要的意义。 本论文中，首先对铸件铸造过程中的相关工艺进行计算以及设计，用SolidWorks进行三维建模，并导出*stl格式文件AnyCasting软件对其进行一系列的参数设置，完成对铸件的前期处理后，开始着重分析铸造过程中充型、凝固过程，及其速度场、温度场的变化情况，并针对结果进行工艺的优化，再次模拟，分析整个充型、凝固过程，并与前方案的处理结果进行从而确定其最优方案。主要结论如下： 铸造的过程中浇注方案的优劣直接影响铸件的成品率以及铸造 运用软件对铸件及浇注系统的三维设计是模拟的前期准备，绘制的准确度直接影响后期的模拟结果 AnyCasting软件对模拟能比较准确的反应铸件的实际情况，预测可能产生的铸造缺陷及缺陷部位 根据铸造模拟的结果，优化铸造工艺，然后分析结果再次优化方案，最终确定最优方案。 关键词：SolidWorks建模；AnyCasting软件；铸造 Based on the valve cover of AnyCasting casting process simulation ABSTRACT:With the development of computer technology and numerical calculation technology, the computer in the field of casting has been widely research and application.It can not make actual casting, simulate the filling and solidification of casting, heat transfer, stress field and microstructure distribution, such as the formation of shrinkage cavity and shrinkage process, can greatly improve the production efficiency and economic benefits, is of great significance for casting production. This thesis, first of all the related in the process of metal casting process design, calculation and using SolidWorks entity modeling, and export * STL format file using AnyCasting software to a series of parameter Settings, the early stage of the finish for the castings after processing, the simulation. Emphatically analyzed in the process of casting filling and solidification process, and the changes of the velocity field, temperature field, and the simulation results for the optimization of casting process, simulation again, analysis of the filling and solidification process, and compared with the former scheme of treatment results. To improve again for optimized solutions so as to determine the optimal solution. Main conclusions are as follows: (1) The process of casting pouring scheme of fit and unfit quality directly affect the yield of the casting and the size of the casting cost;
