Abstract

This study integrates surrogate models into combined design optimization of a binder cover, considering production cost and performance constraints. Results reveal that models trained on substantial datasets achieve designs close to the global optimum. Incorporating model variance into constraints prediction in surrogate-based optimization improves robustness and accuracy, especially with noisy functions. This modification enhances the likelihood of obtaining feasible designs, reducing computational demands and showcasing the potential of smaller datasets in predicting local optima.

Abstract

Pedestrian bridges are an important part of the urban infrastructure that ensures the safety and comfort of pedestrians. They have a number of distinctive features compared to road bridges. Also, the pedestrian load itself has a significant dynamic component, which can lead to the occurrence of resonant phenomena. Composite reinforced concrete bridges are widely used among the road bridges. This is due to the possibility of including the roadway structure in the act, which increases the load-bearing capacity and reliability of the structure. The same advantages are typical for pedestrian aboveground overpasses. However, pedestrian bridges have a number of features that affect the operation of the composite reinforced concrete structure. It is well-known that the difference between bending structures in civil construction and bending structures in bridge and road construction is the ratio of the rigidness of the concrete and steel parts. The load on pedestrian aboveground overpasses is similar to the temporary load in civil buildings, adjusted for a large dynamic component. But at the same time, the spans of pedestrian aboveground overpasses are similar to the spans of road bridges. In this article, the prospects for the development of composite reinforced concrete structures of pedestrian overpasses are reviewed.

Abstract

Most companies do not take assembly aspects of a product into account during the early design process. This often results in designs that are optimal from a performance point of view, but are hard or impossible to assemble. This leads to numerous design changes late in the product development process, causing significant extra costs. To solve this issue, a co-optimization framework is developed that takes into account the assemblability as a constraint during the performance optimization. The presented framework is applied to minimize the mass of a gearbox with constraints on the axle stiffness and the first resonance frequency of the housing, while also respecting a set of assembly rules. The assembly rules take into account the complexity of the assembly, for instance the number of unique standard parts used and geometric properties like weight and dimensions.In each iteration, the performance of the design is evaluated with a parametrized finite element model, while a numerical assemblability score of the current design is estimated based on the assembly STP file. The obtained performance and assemblability metrics and their combination serves as a constraints and objective function for the design optimization. ispartof: pages:2753-2762 ispartof: Proceeding of ISMA2020 including USD2020 pages:2753-2762 ispartof: ISMA-USD Noise and Vibration Engineering Conference 2020 location:Leuven, Belgium (Virtual event) date:7 Sep - 9 Sep 2020 status: published
