| Abstract: | A new type parallel machine tool is the creative application of the spatial multi loop mechanism in the field of machine tools. Considering the elastic influence of machine tool members, a finite element analysis model of elastic dynamics is presented. Meanwhile this paper still analyzes the natural characteristics and dynamic response of the machine tool based on several typical structure cases, the relation between structure cases and dynamic characteristics of the machine tool is obtained. These research work provides basis for dynamic design of machine tools. |
