Estudo comparativo entre modelagens de prendedores para juntas triplas aeronáuticas.

Abstract

The need to build extremely safe aircraft and demonstrate it through analysis and testing is crucial within the aeronautical market. Therefore, this work aims to conduct a comparative study among three different methodologies for modeling fasteners in joints. These joints have different compositions the first composed of plate/plate/plate and the second of solid/plate/solid. Considering the main objective of evaluating the total load transfer for each component in the developed model, including the percentage of total load applied to the first two upper pieces on their right side, in addition to the load on the critical fastener. The goal is to understand which of the three modeling types is more conservative in relation to the results. Additionally, data will be collected to analyze the load on each of the fasteners developed, comparing their similarities and effectiveness. This will help identify the most conservative fastener in each of the scenarios studied. Furthermore, the effectiveness of the loads at the left end of the model will be analyzed to understand the behavior across different cases. Finally, a sensitivity study will be conducted to assess the influence of fastener weakness on the model by varying its strength. After completing these procedures, it will be possible to determine which model is most suitable for each situation, considering factors such as working time and the level of modeling complexity.
