Multi-objective topological optimization with multiple constraints for complex structures

Project Member(s): Luo, Z.

Funding or Partner Organisation: Aerospace System Engineering of Shanghai

Start year: 2015

Summary: With the increase of payload weight and function of aircrafts, the structural weight of aircrafts also increases. Accordingly, the carrying capacity of an aircraft (e.g. a rocket) gradually can¿t meet the requirements ofweight and space layout. Therefore, the design optimization, such as the structural lightweight design and topologically layout optimization of components, is becoming more and more important but more difficult in the design of weight-reduced but high-performance aircrafts. Due to various requirements and constraints existing in aircraft design including weight, frequency, intensity, interface, static and dynamic loads, it is a key issue to conduct the multi-objective structural optimization subject to multiple constraints.
