Airborne electronics face harsh environmental, high reliability and high design margin requirements. Mass and volume constraints dictate that the design be more compact than commercial electronics. Proper usage of Finite Element Analysis (FEA) modeling in designing high performance avionics will accomplish the optimized design within limited time and budget constraints. The idea of FEA analysis is to utilize computer calculation power to save time and money over iterative testing of real products. Building one design evaluation unit to calibrate the CAD and analysis model can reduce or eliminate the need for building several costly units in the traditional way. Engineers should learn to evaluate design options on computer models as much as possible instead of on real products. If similar product models have been calibrated before, some stages of mockup can be eliminated and more time and money savings will be achieved. To accurately calculate the vibration response of electronic equipment, precise weight estimation is the most important factor. Weight estimation is the determinative part of vibration analysis. This paper discusses the FEA modeling, design and testing strategies and their relations to weight estimation. This paper proposed two weight estimation methods and showed a few real life examples.
