Methods for selecting appropriate machine vibration criteria
1 Scope
This document provides guidance for the selection of appropriate vibration criteria for a specific machine type, thereby selecting appropriate vibration measurement and evaluation methods: probably
GB/T 6075, GB/T 11348 and other standards related to machine vibration are described:
This document gives an overview of the relevant standards and summarizes their scope of application: It also provides useful instructions for machines without previous experience:
A theoretical basis for determining whether to perform vibration measurements on non-rotating components, rotating shafts, or both: Since there may be
Characteristics exist that lead to the selection of different most appropriate measurement methods, and this document is not intended to supersede the manufacturer's or user's existing actual
Experience:
The purpose of this document is not to equip the reader with all the technical details of the criteria required to perform measurement and evaluation work on a particular machine, but
The reader is guided to select the appropriate criteria, which give the necessary details: Then, with proper training, the reader will be able to
Measure or evaluate work:
