Global Numerical Model of Automobile Gearboxesonents. Gearbox casing behavior is introduced by using substructure analysis, and a tangent stiffness matrix could be defined for each roller body bearing element. This model is used to study the dynamic behaviour of an automobile gearbox. The first studies highlight the influence of the roller bear

Machining Optimization of Quenched Partsculating the post-quenching residual stresses, we develop a numerical method in order to simulate machining by using the mapped stress from the drop forging onto the final part mesh..We then develop a 2D optimization program in order to minimize deformation during machining, depending on the final p

Optimization of a Passive Safety Device by Means of the Response Surface Methodologygrowing attention of the customer for safety. Hence, it is necessary to improve every component of the vehicle to achieve better performance. An effective component in reducing loads transmitted to the driver chest in frontal crashes is the deformable steering wheel column, capable of collapsing wit

Optimal Design of Mechanical Components with Genetic Algorithm known mechanical system, we can formulate the mechanical design problem as an optimization problem, called problem of optimal design. The latter contains non-linear equations, inequality constraints and mixed variables that are continuous and discrete. There are also interdependent discrete paramet

Shape Optimization and Adaptivity of Axisymmetrical Shells Undergoing Geometric Nonlinearitieson, error estimation technique and adaptivity, is proposed. The optimization process is carried out by coupling non-linear FE analysis, B-Spline shape parametrization, sensitivity analysis, mathematical programming and automatic adaptive mesh refinement. An efficient sensitivity analysis is used to

Topological Optimization of Shells with Non Uniform Thicknessesological optimization which has successfully solved industrial situations involving about 3,000 unknowns. In the considered approach, the topology of the structure is characterized by an unknown thickness distribution and the frequency constraint is treated by a dual method.

Design of an Automatic Topology/Geometry Optimization Softwaredvantage is that they generally lead to structures which are difficult to manufacture because they own composite materials, sometimes with intermediate densities. On the other hand, when the layout is fixed, the geometry optimization methods can lead to a good-looking optimum, but cannot change the
