摘要

拓扑优化与增材制造为实现轻质高性能复杂结构提供了全新研制模式。回顾了作者团队近年来围绕拓扑优化与增材制造技术融合研究的相关内容，包括考虑增材制造悬空角、连通性工艺约束的拓扑优化设计方法研究，非均匀点阵结构优化设计方法研究等。以典型民用飞行器结构舱门摇臂及铰链臂结构设计为例，介绍了拓扑优化与增材制造融合技术的工程应用情况。在满足设计指标的前提下，舱门摇臂与铰链臂结构分别减重10%、30%。拓扑优化方法与增材制造技术的融合在航空航天等领域优势明显，但目前以传统的静刚度、静强度等常规承载性能设计为主，工程应用主要集中在功能件和次承力件，未来需要在抗疲劳设计等研究领域进行突破。

Abstract

Topology optimization (TO) additive manufacturing (AM) provide a complete innovation methodology for lightweight and high-performance complicated structures. This paper reviews the recent research on the integration of TO and AM

including the TO method considering AM processing constraints

the optimization method of non-uniform lattice structure. Furthermore

the integration of TO and AM is typically applied in civil aircraft structural design. Taking the structural design of hatch rocker arm and hinge arm as examples

while meeting the design indicators

the weight of hatch rocker arm and hinge arm structure were reduced by 10% and 30%

respectively. Finally

the integration of TO and AM shows obvious advantages in aerospace and other fields. However

the conventional design methods such as traditional static stiffness and static strength are mainly used

currently

and the industry application are focused on functional parts and secondary load-bearing parts. In the future

breakthroughs are needed in the fields such as fatigue-resistant design of AM structures.
