Identi­fy­ing Dan­ger­ous Vibra­tions in Pro­duc­tion Lines

For re­li­able op­er­a­tion

The cur­rent trend in pro­duc­tion tech­no­logy tends strongly to­wards fully auto­mat­ic and autonom­ous ma­chines in line with in­dustry 4.0. This en­ables com­pan­ies not only to design their pro­duc­tion more ef­fi­ciently, but also to react flex­ibly to the needs of the mar­ket. Des­pite all the latest de­vel­op­ments, basic ma­chine ele­ments are still to be found in most fully auto­mat­ic­ally con­trolled sys­tems, since en­ergy has still to be con­ver­ted into its vari­ous forms. However, this is pre­cisely where chal­lenges with a wide vari­ety of vi­bra­tions occur.

Res­on­ance Vibra­tions

Poten­tial dam­age in pro­duc­tion lines

A pro­duc­tion line rep­res­ents a very com­plex struc­ture of many com­pon­ents and thus a com­plex multi-mass sys­tem with dif­fer­ent vi­bra­tion modes or nat­ur­al fre­quen­cies. Cer­tain ex­cit­a­tions lead to vi­bra­tions, for ex­ample in rollers or shafts. At a cer­tain de­gree of vi­bra­tion, how­ever, mal­func­tions occur be­cause the fully auto­mated po­s­i­tion­ing sys­tems can no longer func­tion prop­erly. In the worst case, these in­duced mis­align­ments can lead to costly pro­duc­tion down­times. At the same time, vi­bra­tions may cause ex­pens­ive dam­age to ma­ter­i­als such as gears.

The ques­tion arises: Where does the prob­lem res­ult from? How can faults be cor­rec­ted to en­sure smooth op­er­a­tion?

Meas­ure­ment & Ana­lys­is Tech­no­logy to Pre­vent Dan­ger­ous Vibra­tions

Our solu­tion Against harm­ful Vibra­tions in Pro­duc­tion lines

Long-term vi­bra­tion re­cord­ing par­al­lel to ma­chine or op­er­at­ing data and sub­sequent eval­u­ation de­liv­ers valu­able in­form­a­tion about the causes of the haz­ard­ous vi­bra­tions. On this basis, cor­rect­ive meas­ures can be taken. In the spe­cif­ic case of pro­duc­tion lines, these range from im­proved damp­ing over elim­in­at­ing com­pon­ent mis­align­ments to chan­ging mech­an­ic­al set­tings.

With the IfTA Dy­n­aMas­ter for mo­bile long-term data ac­quis­i­tion and the cor­res­pond­ing ana­lys­is soft­ware IfTA TrendView­er, causes can be found ef­fi­ciently. The IfTA sys­tem cre­ates trans­par­ency and an over­view of large amounts of data. This en­ables the ne­ces­sary data eval­u­ation, which is the basis for pro­cess op­tim­iz­a­tion and auto­ma­tion. To pre­vent mal­func­tions from oc­cur­ring again, IfTA Ar­gusOMDS of­fers ad­di­tion­al pro­tec­tion and per­man­ent long-term mon­it­or­ing of the plant/ma­chine (also avail­able as an up­grade for IfTA Dy­n­aMas­ter).
