摘　　要：出于结构的可制造性考虑,以提高双相材料结构的强度、稳定性和耐久性等性能为目标,本文利用拓扑优化方法研究了通过接头连接的双相材料结构。在显式拓扑框架下添加了“接头”作为优化的基础构件,构造了双相材料的材料属性插值模型,建立了可同时优化材料属性和结构布局的拓扑优化模型。通过对双相材料结构进行优化设计,实现在保证结构强度的同时减轻结构重量、降低材料成本等目的,为实际工程应用提供一定的理论和技术支持。For the consideration of the structural manufacturability,and aiming to improve the strength,stability and durability of the biphasic material structure,this paper uses the topology optimization method to study the biphasic material structure connected by joints.Under the explicit topology framework,“joint”is added as the basic component of optimization,to construct the material attribute interpolation model of the biphasic material,and establish the topology optimization model that can optimize both the material attributes and structural layout.Through the optimization design of the biphasic material structure,the purpose of reducing the weight of the structure and reducing the material cost while ensuring the strength of the structure is achieved,providing certain theoretical and technical support for practical engineering application.
