Vibration Severity Criteria. Vibration Severity Chart Vibration Engineering And Design Vibration Severity Chart to determine acceptability of vibration levels measured Values shown are for filtered readings taken on the machine structure or bearing cap When using the Machinery Vibration Severity Chart thefollowing factors must be taken into consideration 1.

Besides the main sources of vibration are listed putting emphasis in three due to is importance when measuring vibration within condition monitoring of spindles These are imbalance bearing damage and critical speed Later relevant concepts of vibration technology and signal analysis are introduced.
