Análise numérica de um atuador passivo lmf para um mastro de sonda de produção de petroleo

Abstract

The present work presents a numerical evaluation of a rectangular shaped tube actuator for the containment of high stresses in probe production mast, using the finite element method. In the midst of a high magnitude load scenario, the oil production probe masts are critical components for the safety and performance of the entire probe, since, together with the substructures and bases, they sustain the highest loads coming from the activities of the probes. Thus, in order to adapt a mast to the design standards established by the API 4F, through the finite element method, a passive actuator made in a shape memory alloy was evaluated, starting from the determination of critical regions of the mast, passing through evaluations of actuator performance and ending with a comparison between the part made of shape memory alloy and commercial steel. Such an actuator was able to act at the critical points of the mast, reducing the stress levels when it was subjected to its maximum capacity.
