Simulation by the Finite Element Method of the Vibratory behaviour of a Rotor

This article is dedicated to the study of the vibratory behavior of a rotor. The study presents a set of scientific techniques on modeling and simulation of the vibrations of a rotor of a turbomachinery driven in torsion. (...)

Study of the turbulence models over an aircraft wing

Aerodynamics is defined as the science of handling a fluid that is often the air interacting with a structure. When simulating the flow over airfoils, transition from laminar to turbulent flow plays an important role in (...)

CFD Analysis of the Transonic Flow over a NACA 0012 Airfoil

Computational Fluid Dynamics (CFD) incorporates mathematical relations and algorithms to analyze and solve the problems regarding fluid flow. CFD analysis of an airfoil produces results such as lift and drag forces which (...)

Reliability-based design optimization analysis of a piezoelectric engine

In this paper, we study extensions of the RBDO of the piezoelectric engines with travelling wave taking into account the dynamic contact between the different components (stator and rotor). Generally, the life of these (...)

Contribution of the Runge Kutta order 4 method in the dynamic of Mechanical System

The purpose of this article is to solve the differential equations of Lagrange of a discrete system. Indeed, modeling and simulation are important steps in mechanical analysis. Modeling makes it possible to write the (...)

An equivalent isotropic approximation for reliability-based design of mini-plate fixation used in fractured mandibles

The objective of this work is to assess the reliability level of mini-plate fixation following surgical operation. A 3-dimensional finite element model is developed in order to study the negative effect due to the (...)

Experimental characterization of hydroforming

The shaping by the hydroforming process involves several complex phenomena and presents several types of non-linearities (geometric, material, etc.). The development of a hydroforming operation requires a lot of tests to (...)

Modeling and numerical simulation of hydroforming

The hydroforming process is strong in its technological advantages; it is nonetheless true that a good control of this process is vital for its development. In an increasingly competitive industrial environment, automakers (...)

An aerodynamic Study of wind turbine blade

Present paper aims to numerically simulate an aerodynamic flow around a wind turbine blade. So two simulations are performed using ANSYS CFX; first, a section of a wind turbine blade subjected to an air flow, using three (...)

Metaheuristic for the RBDO of the brasure’s joints of an electronic board

In the majority of mechatronic devices, thermal fatigue of solder joints is a mechanism causing failure of the solder joints. This type of failure is the main cause that the lifetime of embedded mechatronics systems is (...)
