Analysis and Optimization in Design

Types of analysis in engineering design

There are numerous types of analysis that you can use in the embodiment design, depending on the nature of the designed project and customer’s requirements.

Few examples of different types of the engineering analysis are:

  • Stress, strain, and displacement

Finite element analysis allows to reduce stress concentrations. Knowing the results of stress distribution simulation, you can redesign critical sections, for example, add fillets to avoid stress concentrations in sharp corners.

  • Vibration analysis

There are many major sources of vibrations that may occur in a system. Some frequencies, that are called natural, are intrinsic to all objects, others may appear due to specific peculiarities of an object, e.g., whirling. Various vibration causes can be addressed during mechanical design, others require proper selection of components and operating modes.

  • Thermal analysis

Another widely used type of analysis is thermal, for example, for the evaluation of thermal performance of the battery module of an electric vehicle.

  • Computational fluid dynamics analysis

Computational Fluid Dynamics (CFD) is the analysis of fluid flows using numerical solution methods. With the help of CFD, you can analyze complex problems related to fluid-fluid, fluid-solid and fluid-gas interaction.

Optimization in Engineering Design

Optimization is often used during engineering design process. It is a systematic process that uses design constraints and criteria to allow finding an optimal solution. A wide range of optimization techniques and methods is available for researchers and designers. Despite the importance of optimization for the engineering design, introduction of various optimization techniques is not the scope of this web site, and you can find multiple resources for the optimization methods elsewhere.
