Dy­nam­ic Com­po­nent Be­hav­ior on the Best Bench

Time- and data-in­ten­sive in­ves­ti­ga­tion of dy­nam­ic load lim­its

A shak­er table is a tech­ni­cal test­ing de­vice used to in­ves­ti­gate the in­flu­ence of vi­bra­tions on com­po­nents or ma­chines. As an ex­em­plary ex­am­ple, a shak­er table test stand of the com­pa­ny Ake-tech­nolo­gies is shown on the left.

Shak­ers can be used to test the com­po­nent be­hav­ior under dy­nam­ic loads in order to ob­tain in­for­ma­tion about its fa­tigue strength lim­its and load lim­its. How­ev­er, such a test pro­ce­dure takes a lot of time. A long-term mea­sure­ment with a suit­able mea­sur­ing and anal­y­sis sys­tem is es­sen­tial for de­ter­min­ing the caus­es and the exact time of the oc­cur­rence of dam­age.

The Right Tim­ing

Chal­lenges on shak­er ta­bles

The real chal­lenge of long-term mea­sure­ments with shak­er table test bench­es is the pro­cess­ing of the large amounts of data that occur dur­ing long-term mea­sure­ments. On the one hand, data should be easy to process for rapid de­tec­tion of fail­ures. On the other hand, the data set must have a high res­o­lu­tion for the anal­y­sis of vi­bra­tion modes and de­for­ma­tions caused by the dy­nam­ic load. Trig­gered stor­age, i.e. event-based stor­age, is only rec­om­mend­ed if the trig­ger thresh­old is known. Other­wise, a com­pro­mise must be made be­tween the amount of data and the res­o­lu­tion.

Our so­lu­tion for shak­er ta­bles

An all-in-one mon­i­tor­ing sys­tem in con­junc­tion with an anal­y­sis soft­ware that solves this ac­tu­al con­tra­dic­tion be­tween ac­cu­ra­cy and speed of the data anal­y­sis. With the AD4Pro input mod­ule, ac­celerom­e­ters and strain gauges can be read di­rect­ly with­out ad­di­tion­al elec­tron­ics.

Our sys­tem so­lu­tions in com­bi­na­tion with the anal­y­sis soft­ware IfTA TrendView­er en­able a very easy han­dling of large amounts of data, which are gen­er­at­ed dur­ing long-term mea­sure­ments on vi­bra­tion table test bench­es. Based on the con­tin­u­ous stor­age, mea­sure­ments over long pe­ri­ods of time are pos­si­ble with­out any prob­lems. Com­pact over­view files allow fast search­ing for events and thus ef­fi­cient work­ing.
