| Popis: | Experimental modal analysis has received a lot of consideration in recent days for dynamic analysis of complicated engineering structure and machine tools. It is a process which is used to determine the inherent dynamic properties of structure such as damping, mode shapes and natural frequencies. The experimental modal analysis benefits in design of all types of structures including automotive components, aircraft components, spacecraft, computers and tennis rackets and golf clubs etc. The present study deals with the experimental investigation of free vibration of milling machine arbor. Experimental modal analysis of milling machine arbor is carried out by using laser vibrometer for measurement and impact hammer for excitation. The experimental results are compared with the numerical predictions obtained using finite element modeling software ANSYS workbench 14.5. The scope of present work is to understand and investigate the modal parameters of milling machine arbor in the form of natural frequency and mode shape for robust design. |
