vibration analysis picks up increases in vibration levels that are too slight for the ear to detect or the hand to feel. By monitoring, measuring and analyzing those vibrations, users can often pinpoint the ex-act cause of the problem and cor - rect it before real damage occurs. Vibration analysis and oil analysis are rarely performed to-

vibration. Today, random vibration is thought of as the random motion of a structure excited by a random input. The mathematical theory of random vibration is essential to the realistic modeling of structural dynamic systems. This article summarizes the work of some key contributors to the theory of random vibration from

PRÜFTECHNIK AG Vibration Handbook 5 Introduction to vibration measurement The fundamental physical source of this vibration and of the recorded signal could be thought of, for example, as follows: The vibration velocity v is the change in displacement x over a period of time. Its waveform is shifted by 90 from the position

The dynamic vibration tests on structures are generally subdivided into two groups: (a) forced vibration test and (b) ambient vibration test. In the forced vibration test, the structure is usually excited by artificial means. The excita

The ISO 2631 suggests vibration measure-ments in the three translational axes on the seat pan, but only the axis with the greatest vibration is used to estimate vibration severity.5 The current trend in vibration research is to use multi-axis val-ues.

To prevent hydraulic systems from breaking down, analysis of their vibration is required. An e ective method of reduc-ing vibration and noise needs to be developed: its aim is to improve the performance of hydraulic devices and thus reduce the vibration and noise in hydraulic systems. Vibra-tion and noise arise from the interaction between solids

As Equation 1 shows, vibration can only change as the result of two things: a change in force or a change in stiffness (or both). In other words, vibration is merely a result of other root causes occurring in a .
