Long-term Tests for Ana­lys­is and Op­tim­iz­a­tion

Data flood from the sim­u­la­tion of loads

Dur­ing their ser­vice life, com­pon­ents are nor­mally sub­ject to a wide vari­ety of loads, which must al­ways be met, wheth­er stat­ic or dy­nam­ic. In order to be able to test the ac­tu­al be­ha­vi­or of a com­pon­ent under dy­nam­ic con­di­tions, long-term tests or en­dur­ance tests are also car­ried out dur­ing the de­vel­op­ment phase of a com­pon­ent. However, dy­nam­ic meas­ure­ments gen­er­ate enorm­ous amounts of data, which lead to the fol­low­ing con­flict.

Pre­ci­sion vs. Com­pu­ta­tion­al Ef­fort

Chal­lenges in long-term test­ing

On the one hand, due to clar­ity, it should be pos­sible to quickly ana­lyze all data of the vi­bra­tion be­ha­vi­or over the en­tire peri­od, but on the other hand, the data set must be avail­able in a high res­ol­u­tion for un­der­stand­ing the cor­rel­a­tions of the vi­bra­tion be­ha­vi­or. The un­der­ly­ing con­flict is there­fore to find the right com­prom­ise between stor­age/ com­pu­ta­tion ef­fort and ac­cur­acy when meas­ur­ing vi­bra­tion over a long peri­od of time.

Un­com­prom­ising meas­ure­ment and ana­lys­is tech­no­logy for long-term tests

Our solu­tion

A mon­it­or­ing sys­tem in com­bin­a­tion with an ana­lys­is soft­ware, which solves this ac­tu­al con­tra­dic­tion and at the same time im­presses with the ac­cur­acy and speed of the data ana­lys­is.

The IfTA sys­tems in com­bin­a­tion with the ana­lys­is soft­ware IfTA TrendView­er en­able a very simple hand­ling of large amounts of data, such as those gen­er­ated in long-term tests of com­pon­ents. The ac­tu­al con­tra­dic­tion between large amounts of data (com­put­ing ef­fort) and fast ana­lys­is is solved in a very el­eg­ant way. Depend­ing on the pur­pose of the ana­lys­is, the data can be viewed in dif­fer­ent modes. In order to cap­ture the en­tire time peri­od, it is suf­fi­cient to dis­play the data with a lower res­ol­u­tion, whereby it is pos­sible to zoom to cer­tain points with the highest res­ol­u­tion if re­quired. Thus, very large amounts of data for long-term vi­bra­tion ana­lys­is can be pro­cessed un­com­prom­isingly.
