A Simplified Approach to Modal Analysis of Machine Tool Structures

Vibration characterisation of machine tools is essential to keep their operating frequencies away from their natural frequencies thus avoiding resonance. Modelling and analysis of the actual structure are expensive time-consuming and require more computational efforts. Therefore it seems logical to develop a simplified method using which the natural frequencies and modes shapes of the machine tool structures can be approximated quickly and economically. This book presents a FEM based simplified methodology using which the vibration characteristics of the machine tool structures can be ascertained with reasonable accuracy.
