What if this is not possible?
Sometimes there are valid reason why this approach cannot be followed, like:-
The approach must be implemented via a closed feedback loop process, and over a long period of time. Building these capabilities takes time, but becomes a true investment for the future, as the constraints and assumptions taken for modelling are refined by the experimental results, and can be used for future modelling.
A good example of this, is a electronic circuit on a printed circuit board (PCB).
In our experience, during flight certification using RTCA/DO-160 and Mil-Std-810, there are components that fail during vibration testing on a vibration shaker.
These are usually
Fine wired components
Internals of components
Relatively heavy components detaching
Capacitor legs fatiguing due to vibration
Ceramic components cracking
These are typical failures that we have seen over the last 25 years on PCBs…
We have generated a lessons learnt database that assists us in solving these failures cost effectively, and quickly.
There are also other aspects that contribute to failures on PCBs. And they are:
Designers not adequately informed of the complete nature of the tests that the component will undergo
A lack of structural dynamics understanding
The incorrect fixings and the locations of the mounts or stand-offs
This is where the true understanding of structural dynamics is an asset to any design and manufacturing company.
