The material selection evaluation based on material database can bring database full play in the mass memory and the powerful search function,and can give computer full play in the supercomputing power.Since such,the old complex process,which is the selection of the evaluating material and mass data initialization and model calculation,becomes shortcut,exact,simple and intelligent.On the base of the material database system construction,the functional module of the material adaptability evaluation method was developed,and the computer aided selection evaluation of material based on the material database was realized.This is a beneficial try in the direction of the material database system intelligent development.The attained quantified evaluation results directly reflect the difference between the close property and different property of the material selection schemes.The subjectivity and blindness which are generated when the material selection is only based on the experience decrease.基于材料数据库的选材评价,可以充分发挥数据库海量存贮能力、强大的检索功能与计算机的超级计算能力,使待评价材料的筛选和大量数据初始化处理与模型计算等评价的繁琐复杂过程变得快捷、准确、简便和智能。在构建材料数据库系统的基础上,开发出材料适用性评价方法功能模块,实现了基于材料数据库的计算机辅助选材评价,在材料数据库系统向智能化技术发展的方向上进行了有益的尝试。通过评价得到的量化结果,直观反映出性能相近或各有优劣的选材方案的差异,减少了仅凭经验甄别选材方案时的主观性或盲目性。
