“…Además, dentro de las principales virtudes de la Ingeniería asistida por computador (Computer-Aided Engineering -CAE), está la accesibilidad a velocidades computacionales mejoradas que otorgan los softwares comerciales [7]. Igualmente, las simulaciones de elementos finitos son más intuitivas, completas y ayudan ahorrar tiempo y costos [8].…”

Objetivo: En esta investigación, se diseñó y simuló un trineo de carga para equipos e insumos en el sector petróleo y gas. Metodología: Inicialmente, se definió la geometría del trineo con base a las restricciones establecidas, en la cual se evaluaron la magnitud y el lugar de aplicación de las fuerzas en condiciones de servicio. Posteriormente, mediante el método de Pugsley se halló el factor de seguridad, con el propósito de evitar falla de tipo estática como resultado de la aplicación de cargas. Se generó el modelo geométrico, la discretización y la simulación bajo cargas estimadas empleando el método de elementos finitos, y los recursos computacionales de softwares CAD/CAE. Resultados: Finalmente, se representaron los resultados del análisis por medio de trazados de esfuerzo, deformación y factor de seguridad, comparando con el método de Pugsley para así definir la carga que debe transportar la estructura. Conclusiones: Se definió 2000Kgf como carga máxima, ya que garantiza la seguridad de uso del trineo.

“…When complex boundary conditions and loads have to be considered, numerical simulations such as finite-difference method and finite-element analysis (FEA) are generally suggested to obtain a detailed 3D deflection and stress field. For example, Song [ 25 ] explored the deflection and stress characteristics of standing seam metal roof panel under different negative pressure load by FEA software. Wang [ 26 ] applied a cube finite element model to analyze the piezothermoelasticity of an intelligent thin plate.…”

Metal roof sheathings are widely employed in large-span buildings because of their light weight, high strength and corrosion resistance. However, their severe working environment may lead to deformation, leakage and wind-lift, etc. Thus, predicting these damages in advance and taking maintenance measures accordingly has become important to avoid economic losses and personal injuries. Conventionally, the health monitoring of metal roofs mainly relies on manual inspection, which unavoidably compromises the working efficiency and cannot diagnose and predict possible failures in time. Thus, we proposed a novel damage monitoring scheme implemented by laying bend sensors on vital points of metal roofs to precisely monitor the deformation in real time. A fast reconstruction model based on improved Levy-type solution is established to estimate the overall deflection distribution from the measured data. A standing seam metal roof under wind pressure is modeled as an elastic thin plate with a uniform load and symmetrical boundaries. The superposition method and Levy solution are adopted to obtain the analytical model that can converge quickly through simplifying an infinite series. The truncation error of this model is further analyzed. Simulation and experiments are carried out. They show that the proposed model is in reasonable agreement with the experimental results.

“…The numerical models are frequently carried out to simulate the complicated weather conditions like fluctuating wind, snow, rain and temperature variation. Thus, more precise analysis for deflection and stain characteristics of metal roofs and connected joints under various weather loads were studied in [3,4], and the results can be used as a reference for pre-design and reliability analysis of buildings. Furthermore, modeling the wind pressure distribution is the most effective method of choosing the location of detection nodes for real-time monitoring system, because it is often impractical in large-span buildings to cover all a roof surface by laying sensors in quantity.…”
