Multilevel Optimization of a Morphing Structure Incorporating Shape Memory Alloy Wires Conference Paper uri icon


  • A methodology for optimizing a morphing structure, based on Shape Memory Alloy actuators is presented in this work. This work aims to define an efficient design that exploits the actuator capabilities in a reasonable range of the component loading. To this end, the optimization process is split in two levels. In the first level the tailoring of the structure's compliance is pursued, while in the second one the sizing of the actuators takes place. The combination of the modeling tools that are used is described. An aerospace component in a turbofan engine is considered as the demonstration model. The outcome of this study proves that the methodology followed is capable of producing satisfactory results for morphing structures incorporating Shape Memory Alloy actuators in a time efficient way. © 2013 by Dimitris A.
