About the Lecture:

3D lattice structure is considered to be one of the most promising lightweight multifunctional structures for the next-generation spacecraft. Thanks to the development of additive manufacturing technology, high-precision 3D lattice structure can be manufactured in recent years. However, the lack of structured design method for additive manufacturing in spacecraft 3D lattice structure leads to difficulties in performance-based design, quality formulation and performance prediction of gradient structure, which seriously restricts the application of 3D lattice structure in the field of aerospace.

Inspired by crystal symmetry, we proposed and adopted the design method of self-supporting 3D lattice structure and its gradient structure and the resonance frequency prediction method based on CT scanning and stiffness equivalence. These methods enabled us to complete the design and development of several types of lightweight multi-functional structures, such as the main bearing structure of Qiancheng 01 satellite, reducing the structure weight by more than 30% to 50% and increasing the thermal energy storage capacity by more than 50%. As the demonstration of the upgrading of spacecraft structures in China, some models been successfully launched into the space.
