| Abstract |
This paper focuses on the performance optimization of the control surfaces of aircraft.
A two-scale optimization design method to enhance the mechanical properties of the control surfaces
is proposed. Firstly, the topology optimization of the control surface structure is carried out to find the
main load-bearing areas. Secondly, the periodic microstructure with the optimal stiffness is designed
by joint optimization. After the above work is completed, the optimization results of the first step are
reconstructed for the convenience of design and manufacturing. The periodic microstructures optimized in the second step are selectively filled according to the areas with concentrated material density, so as to obtain the configuration of the two-scale topology optimization design. By analyzing several structures, the obtained configuration is compared with the single-optimization configuration,
the filled configuration and the traditional configuration respectively. The mechanical properties of
the two-scale configuration are significantly improved under the premise of equivalent mass. Therefore, the numerical example results prove the effectiveness of the two-scale design combining macro
and micro structure optimization. |
