Abstract
This paper deals with design problems of a complex technical system. Thus, a new design approach is proposed, which the consideration of static and dynamic requirements is done simultaneously and globally in the preliminary design phase. The proposed design approach is applied on the sizing case of an active MacPherson suspension system. Indeed, in this work, we succeed to integrate the dynamic behavior of the MacPherson suspension in the early design stage. In addition, its dynamic requirements are formalized in the form of algebraic constraints defined by a set of equations and inequalities. The generated solution is the set of acceptable values of design variables satisfying simultaneously static and dynamic requirements. This coupling between the static and dynamic sizing steps in the proposed design approach avoids over-sizing of the system. It also avoids resizing loops in case of failure, which saves significant computation time and reduces the cost of design.
