基于数据库的陶瓷材料计算机辅助设计

COMPUTER AIDED DESIGN OF CERAMIC MATERIALS BASED ON THE DATABASE

根据已知文献的数据建立了陶瓷材料性能和组分数据库 ,开发了管理和操纵该数据库的应用程序 ,利用该程序可以查询已知陶瓷材料系统性能与组分的关系 ;建立了基于该数据库的人工神经网络预测模型 ,通过操纵陶瓷材料数据库中相关数据 ,并结合人工神经网络预测模型程序可以预测未知材料系统在给定性能条件下的各相组分 ,预测了Al2 O3 (W ,Ti)C陶瓷材料在两种目标性能下的组分 ,并计算了其预测误差 ,结果表明 ,其实验值与预测值较为吻合。

A database for the properties and components of ceramic materials according to the known papers has been established,and the application program to manipulate and control this database was developed.Based on the database,a artificaial neural network model to predict the components of unknown material system under the given property conditions has been established,and this model can greatly reduce the developing time of unknown material system.
