Abstract: In this paper, a research of precision CNC turning center’s spindle is presented. Spring damper elements are used to simulate the supports of dynamic and static hydraulic bearing, and the 3D finite element models of the spindle is built. Based on finite element models of spindle, the static analysis and model analysis are performed, and the static stiffness, natural frequency and modes of vibration are put forward. The strain and stress of spindle is explored, and mode of vibration of spindle under resonance and designed working conditions is contrasted.

Abstract: Product information technology has been widely applied in manufacturing field, improved the rapid response ability of enterprises to the market demands, and to some extent enhanced the competitiveness of enterprise products. However, product data information generated by different information system has the characteristics of diversification and differentiation. The integration and management of these product heterogeneous data has become the bottleneck which restricts the development of enterprise information technology. Based on XML, this paper researches the integration and management of heterogeneous data, expounds integration structure of heterogeneous data, introduces integration process and schema mapping of heterogeneous data, and realizes schema translation of heterogeneous data. Finally, through the PLM XML schema which is provided by the product life-cycle management software, this paper verifies the integrated management of relational heterogeneous data on Teamcenter.

Abstract: It is the key step to construct the fuzzy complementary judgment matrix and rank the weighting of the judgment matrix when we apply the fuzzy analytic hierarchy process (FAHP). In this paper, a method of rank the weighting which is based on the idea of additive consistent fuzzy complementary judgment matrix and Euclidean space distance, namely the Euclidean space distance weighting ranking method (EDWM) is recommended. In the end of this paper, a case is given to verify the feasibility and accuracy of this method.
