| Summary: | This experimental work shows that highly detailed and time consuming FE models are not necessary to accurately predict circuit board vibration response. Instead, the paper shows that it is more appropriate to have a good understanding of what factors influence FE modelling accuracy and it gives techniques on how to mitigate or account for them. Using the techniques in this paper will save a great deal of modelling time and also improve result accuracy. The surprising amount of variation in the response of identical circuit boards is also shown. The work is valid for all circuit boards and also for bolted laminated flat panel structures. |
