Many engineering problems involve design optimization subject to constraints. Today, design optimization plays a key role in structural design and has a wide variety of applications in practical real world problems. Applications include optimizing spacecraft, aircraft, and automobile components, increasing the stiffness of a structure and reducing its weight, without sacrificing structural integrity. The lighter structure has a significant positive impact on enhancing performance and cost efficiency. A very common application of a structural optimization problem arises in finding minimal weight design with constraints on stress and deflection. Real world applications such as designing trusses, bridges, and structural components can be formulated and solved as an engineering optimization problem. The goal of the project is to implement a mathematical algorithm and computational analysis method for solving different types of trusses. The SolidWorks simulation software will be used for creating a computer aided design (CAD) and simulating different truss models. The optimal solutions resulted from analytical and computational methods are analyzed and compared for accuracy. Finally, the optimal design of the various trusses with new variables such as weight and stiffness are compared with original designs. This project will have positive impacts on training and educating students in areas of design optimization and computational methods. Future research includes extending the proposed methods of optimization to different types of real world structures such as beams, bridges, and other structural components.
