Design Optimization
Design optimization is a systematic process aimed at achieving the best design solutions by formulating objectives and constraints. It enhances performance, reduces costs, improves reliability and safety, and catalyzes faster development cycles. The chapter covers the integration of computer-aided design tools with optimization algorithms, emphasizing the significance of primary and subsidiary design equations and limit equations in achieving feasible solutions.

What we have learnt
- Design optimization balances performance, cost, and reliability.
- The primary design equation (PDE) defines the main objective, while subsidiary design equations (SDEs) handle additional constraints.
- Limit equations set permissible boundaries for design variables ensuring safety and compliance.
Key Concepts
- -- Optimum Design
- A design approach that systematically seeks the best solution by balancing various objectives like cost and performance.
- -- Primary Design Equation (PDE)
- An equation that represents the main objective in a design optimization problem, typically focusing on maximizing or minimizing a specific attribute.
- -- Subsidiary Design Equations (SDE)
- Equations that express additional constraints which a design must meet, such as stress limits and safety factors.
- -- Limit Equations
- Mathematical expressions that define the permissible range of design variables based on safety and functional requirements.
- -- ComputerAided Design Optimization
- The integration of CAD/CAE tools with optimization algorithms to enhance design efficiency and performance.
