Abstract
The purpose of this thesis is to provide a shock absorber design that can be used with all the family vehicles in a single product. Since each product has different characteristics and applications, it has been suggested that the shock absorber be designed in such a way that by changing the internal orifices of shock absorber, It can be used without altering its overall structure in proportion to any member of the product family.
Considering the importance of differences in the characteristics and family structure of a product, it is necessary to consider orifices changes at best to achieve the objectives of the suspension system, which will be investigated in this thesis after presenting the overall structure of the contributing aid for optimal design. Shock absorbers, assuming the same values of common parameters (such as length, diameter, oil properties, etc.) are uniform, and provide the orifices diameter as the only non-common parameter as well as using target functions such as minimizing vertical acceleration, optimization A platform has been developed, for this purpose multi-objective optimization using genetic algorithm And using it, the optimum size of the orifices diameter sections is presented by the family of the product of the national platform. Finally, the results show that in the design of the aid, products with the same structural characteristics, instead of designing and constructing two shock absorbers, can be used only by using a model of assistance and simply by changing the diameter of the awnings in accordance with the product to the desired results for the passenger ride index which is one of the most important issues in the car suspension system.
