How does the 6D testing and analysis approach differ from the traditional applications of both testing and analysis?
In many failure investigation cases, we use Finite Element Analysis as a first step to assess the dynamics of the structure. We do various static, modal. G-loading, response analysis to determine if there’s something we can attribute to the problem. These hints from FEA helps us shortlist the tests we want to do and the transducer map. Sometimes it may be more of an application/customer usage/handling related issue.
We also take into account these considerations. All these information shall be used in the development of a test plan. If we have high suspicion on a certain root cause, we also try to develop fix for those issues in our FE model before the testing, this way when we determine the root cause during the testing we could implement the fix and validate it.
