Original abstract

The paper discusses some practical problems occurring at ISO 10816-1 application in technical practice. Technical diagnosticians find out frequently that the zone boundaries proposed by the standard are not sensitive adequately to the changes in vibrations during operation resulting from a change of technical condition of the machine. The principle of statistical determination of individual operational limits from the measured overall level of RMS vibration velocity (overall level) with utilization of statistical regulation of individual values is also described in the paper. The alarm limit for the overall level (boundary between the B and C zones) in the range 10 Hz to 1,000 Hz is specified in the paper on the basis of measuring of vibrations on the electric motor of Bosch Rexroth hydraulic unit.

Czech abstract

Článek upozorňuje na praktické problémy při aplikaci ISO 10816-1 v technické praxi. Techničtí diagnostici často zjistí, že normou navrhované hranice pásem jsou málo citlivé na změny vibrací v provozu vyvolané změnou technického stavu stroje. Dále je popsán princip statistického určení jednotlivých provozních mezí z naměřených celkových efektivních hodnot rychlosti vibrací s využitím principu statistické regulace individuálních hodnot. Na základě měření vibrací na elektromotoru hydraulického agregátu firmy Bosch Rexroth je v článku stanovena mez výstrahy (hranice mezi pásmem B a C) pro celkovou hodnotu rychlosti kmitání v pásmu 10 Hz až 1000 Hz.
