Engineering Solutions for Better Products

 

What is Engineering Analysis?

Engineering analysis (also known as computer aided engineering, CAE) is the study of a design, especially for a product, to understand or model its performance under the conditions of its normal use. It is typically performed on potential designs before they are built or when a product does not meet an expectation. The analysis creates an understanding that allows for improvements in the design and corrections of performance problems.

Engineering analysis can solve problems and optimize designs before devices are prototyped or built. This preventative step can save (and has saved) thousands or millions of dollars and can reduce design times.

Frequently, engineering analysis is used to demonstrate the quality of a design concept. For example, one company may wish to purchase a design or a device from a second company, and may want to see a performance analysis before committing to a purchase. Similarly, the second company may wish to demonstrate the efficacy of a design to convince a reluctant buyer. 

ARA Engineering uses a variety of engineering analysis tools to solve problems like those above.

What are the tools of engineering analysis?

Three dimensional solid modeling is the construction of a device design in a computer. Typically, solid modeling is the fastest way to design a device so that it can be built. Additionally, simply building the solid model in a computer can identify issues or improve the quality of a design.

Finite Element Analysis (FEA) is a computational method that models a system by dividing it into many small elements and then simulates the movement of forces, heat, or fluid through the system. This analysis can quickly and inexpensively guide an engineer to an optimal or robust device design.

Multiphysics Analysis is another application of FEA that models several physical effects during an event. For example the event could be the movement of a vehicle across a bumpy road and the physical effects could be stresses or buckling in the vehicle's frame.

Dynamic and kinematic event simulation is also a computer based modeling technique that can evaluate the motions of components in a moving assembly. Three dimensional dynamic simulation of a mechanism in motion is a powerful tool to confirm and ‘tune’ a design before building it.

Ray tracing is a computer based tool that traces the paths of light rays through the elements of a optical system. Just like a mechanical system, the performance of optical instruments can be modeled and improved before being built.

Mathematical modeling is a tool that can be used when more complicated system performance issues must be resolved. By this method, the system's overall performance is 'described' by a model that is developed from an understanding of the system. The models are prepared from the physical principles that govern the system's behavior.
