Framed: An Automl Approach for Structural Performance Prediction of Bicycle Frames

SSRN Electronic Journal, 2022
This paper demonstrates how Automated Machine Learning (AutoML) methods can be used as effective surrogate models in engineering design problems. To do so, we consider the challenging problem of structurally-performant bicycle frame design and demonstrate across-the-board dominance by AutoML in regression and classification surrogate modeling tasks. We

ON OPTIMUM DESIGN OF FRAME STRUCTURES

Acta Polytechnica CTU Proceedings, 2020
Optimization of frame structures is formulated as a non-convex optimization problem, which is currently solved to local optimality. In this contribution, we investigate four optimization approaches: (i) general non-linear optimization, (ii) optimality criteria method, (iii) non-linear semidefinite programming, and (iv) polynomial optimization.

Stress-oriented structural optimization for frame structures [PDF]

Graphical Models, 2017
Abstract To fabricate a virtual shape into the real world, the physical strength of the shape is an important consideration. We introduce a framework to consider both the strength and complexity of 3D frame structures. The key to the framework is a stress-oriented analysis and a semi-continuous condition in the shape representation that can both ...

Application of layout optimization technique to large-scale frame structures considering cross-sectional areas of frame members

Nihon Kikai Gakkai ronbunshu, 2019
To design economical frame structures, it is necessary to determine the optimum frame layout and optimum cross-sectional area of each frame member. Although previous studies have proposed a variety of optimization methods, they can be applicable to small-
