提出了理想材料零件的新概念 ,它是指按零件的最佳使用功能要求来设计 ,由呈梯度变化的组织成分和一定规律分布的细结构的材料与均质材料所组合构成的新型材料零件。提出并阐明了理想材料零件的数字化的并行设计制造 (简称数字化设计制造技术 )的方法和理论基础 ;它以材料与零件的一体化、集成化设计制造为主要特点 ,可根据零件功能要求进行零件的外部几何拓扑形状和内部材料组织细结构的并行设计 ,并采用增材制造和去材制造相结合的制造技术 ,按数字化设计的信息 ,一次完成零件内部组织结构和三维形体的制造。指出数字化设计制造将会使人们长期以来设想的按力学、电磁学性能来高效地设计制造新材料零件变为现实 ,在不远的将来定能像设计和建造房屋那样 ,按照所需功能设计制造理想材料零件。
A new concept of ideal material parts is proposed. It refers to the design of the best use of parts according to functional requirements, the composition of the gradient from the organizational composition and a certain regularity of the distribution of fine structure of the material and homogeneous materials composed of new material parts . It puts forward and expounds the method and theoretical foundation of the digital parallel design and manufacture of ideal material parts (referred to as digital design and manufacturing technology). It takes the integration of materials and parts as an integrated design and manufacturing as the main feature, The external geometry topological shape and the internal material fine structure parallel design, and the use of additive manufacturing and manufacturing to the combination of manufacturing technology, according to the digital design of information, the internal organization of the structure and the three-dimensional body to complete the manufacturing. Pointing out that digital design and manufacturing will make it possible to design and manufacture new material parts with high mechanics and electromagnetism envisaged for a long time to become a reality and to design and manufacture the required functions in the near future like designing and building a house Ideal material parts.
