Structural Design Method of a Control Arm with Consideration of Strength
نویسندگان
چکیده
Recently developed automotive components are getting lighter providing a higher fuel efficiency and performance. In this research, the shape of upper control arm was determined by applying the optimization technology. This study considers the static strength in the optimization process. In this study, the kriging interpolation method is adopted to obtain the minimum weight satisfying the static strength constraint. Optimum design of static strength is obtained by the in-house program. MSC.fatigure is used for assessment of the durability life, which is one of the most important criteria in automotive industry. In addition, the real experiments on 1/4 car is conducted to validate the FEM analysis. At last, the correlation of each case about durability life is obtained. Key-Words: Control Arm, Shape Optimization, Kriging, 1/4 car module, Weak Model, VPG (Virtual Proving Ground)

متن کاملEffect of Pile Scouring on the Structural Behavior of a Fixed Jacket Platform with Consideration of Non-linear Pile Seabed Interaction
In offshore structures, most of failures are caused by the lack of sufficient piles strength. Scour phenomena affects the load transition and the pile strength. The necessity of the consideration of scouring phenomena amplifies when the scour depth becomes remarkable, which can endanger the jacket stability. In this paper, a new method is used to consider the pile scouring using nonlinear pusho...

Researches show that the strength criterion is inadequate for design of structures against seismic loads. Since structures yield and experience plastic deformation under strong ground motion, considering structural damage with inelastic behavior may be a considerable criterion for design and control of the structures.In this paper, three steel structures with dual system consisting of intermedi...
