| Abstract: | The lower orders natural frequencies,modes of vibration and damper rates are obtained,based on the experimental modal analysis of the BKX-I parallel kinematic machine and the sensitivity of the machine is analyzed and the unsubstantial parts of the machine are made sure.Some measures about how to improve the dynamic characteristics of the machine are put forward,which provide useful methods for the dynamical design and the optimal dynamic design of the machine structure. |
