| Abstract: | The lower orders natural frequencies, modes of vibration and damper rates can be obtained, and the unsubstantial parts of the machine are made sure, based on the experimental modal and sensitivity analysis of the 6 - DOF Parallel platform. This paper takes the parallel kinematic machine BKX - I as an example, the methods about the experimental modal analysis and sensitivity analysis are studied, some measures about how to improve the dynamic characteristics of the machine are put forward, which provides useful methods for the dynamical design and the optimal dynamic design of the machine structure. |
