Webinar – Finite Element Analysis driven panel optimization
14 November, 2019 @ 4:00 pm - 4:30 pm
HyperSizer Pro is software for the aerospace industry, intended for stress analysis and structural sizing optimization. The goal of this post is to explore the possibilities of HyperSizer Pro to optimize a typical metallic aerospace structure. In this particular example, a simplified interstage model will be optimized.
During this online webinar the possibilities of HyperSizer Pro are explored to optimize an interstage model.
Simulation model of interstage structure
From the performance, operational, interface and design requirements, it is concluded that recurring cost and buckling failure modes are the main design drivers of the interstage along with the lowest possible mass. The proposed concept for the interstage is based on a stiffened shell construction with ring-frames. The simplified stiffened panel construction (see below) consists of an aluminum cone and aluminum ring frame and is modeled with Abaqus.
Optimization of interstage structure
Stiffeners are placed in axial direction on the stiffened panel construction. During the optimization, the location of the stiffeners, the number of stiffeners, the dimensions of the stiffeners and the thickness of the skin will be varied. The amount of ring frames and the dimension of the ring frames are not considered as variables.
The requirements of the stiffened panel construction are the following
– The lowest possible mass
– The first eigenfrequency should be higher than 100 Hz
– The Mises stress for the 4 load cases should not be above 450 MPa
– The first buckling eigenvalue should be higher than 0 (preloading is used in the buckling procedure)
Parametric and sizing optimization
During the webinar, the results are shown from a parametric optimization (Isight) and from HyperSizer Pro (sizing optimization).
