| Abstract: | Through the advanced PULSE instruments of B＆K and the modal analysis software of Me＇scope, the vibration modal testing system was built by the method of pulse excitation. The structural dynamic parameters of the headstock in the NC machine were tested. On-site vibration test of the servicing rig substructure was made, and the frequency response function curve and vibration amplitude of some classes testing spots respect to reference point of the headstock are obtained. Suggestions were given on structure optimization design of the headstock. |
