Integration of Analysis Recommendations with Realistic Design Solutions

Applied Analysis & Technology realizes the traditional

One aspect that is often overlooked when using any analysis procedure, whether it is a textbook or FEM, is that the mathematical models of systems need to be verified before analytical changes can be reliably tested out on paper. Once the analytical model is defined and verified to be correct and accurately represent the actual part or system then “changes” to the design can be evaluated quickly on paper reducing the costly risk of premature prototyping, production changes, or hardware expenditures.

 

Traditional Approaches Using Conventional Hand Techniques


Even for many of today’s high-tech applications
Applied Analysis & Technology realizes that traditional old-school techniques can sometimes produce the best end results. Standard or classical textbook analysis is normally the first avenue of approach to solving any type of engineering problem. Whether it be mechanical, thermal, fluid or any other category of engineering discipline, many simplifying assumptions can usually be made that will enable the use of the textbook approach and lead to sufficiently accurate solutions.

Some of the limitations associated with standard textbook analysis methods are that the types of problems or systems that lend themselves to textbook analysis are for the most part very simple. What this means is systems must be reduced to “equivalent” simple systems that can be readily solved. Since many simplifying assumptions are required in order to reduce the actual system to a model that can be handled by standard hand analysis methods and procedures.

 

FEA Static, Vibrations, Dynamics - Linear, Non-linear & Composite Materials

When mechanical systems become too complex for traditional analysis procedures then more elaborate and intricate methods are needed.

When more exact solutions are required, or the systems to be analyzed cannot be reasonably reduced to simpler systems, by virtue of their complexity, then Finite Element techniques can be utilized. Finite Element Modeling, FEM, techniques can sometimes be expensive and time consuming. But they most often produce the best solutions.

Fatigue, Damage Tolerance, Crack Growth, and Product Life Estimates

Service life predictions are always important when designing any products. When mechanical systems become too complex for traditional analysis procedures then more elaborate and intricate methods are needed. Applied Analysis & Technology uses both classical hand analysis with commercially available damage tolerance programs like NASGRO & AFGROW.

Thermal Analysis & Design: Heat Transfer – Steady State & Transient

During the course of product development, evolution, or enhancement, thermal analysis and design is many times left as something to fix rather that a design parameter to be considered in much the same way one considers stress analysis.

CFD Methods in Fluid Mechanics Aerodynamics

Applied Analysis & Technology uses both classical fluid mechanics and dynamics hand analysis along with computational fluid mechanics, CFD, software to optimize the design of the aerodynamic shapes, fluid flow.

Computer Aided Design

Applied Analysis & Technology can create detailed engineering drawings and specifications any commercially available CAD software package. Being able to create detailed engineering drawings and specifications as well as fabrication of actual physical prototypes is essential to the completion of any engineering design problem.
