Abstract

The dynamic characteristics of parallel 3-TPT machine tool are researched by experiment in this paper. Firstly, the parameters of dynamic characteristic were identified by theoretical analysis. Then vibration model of Parallel Manipulator was built and formed vibration system for experiment analysis. Then, the modal experiment method and steps were introduced, and the experiment parameters also were identified according to the experiment results. The result dates showed that the result dates are validated. So the method is feasible by experimental verification, which provides reference for dynamic optimal design
