The moments transmitted by a universal joint in varying operating condition was investigated. A model of shaft system driven by a universal joint which consists of a driving shaft, a driven shaft and a cross piece is chose. Both structure misalignment and error misalignment between the two shafts at the universal joint was considered, and the study was based on the assumption that friction, inertia and elastic forces of the cross piece were disregarded. Two pairs of Euler angles were introduced to denote structure misalignment and error misalignment respectively, sets of reference frames were built up on the driving shaft, driven shaft and cross piece. Using direction cosine matrixes to describe the relation between different frames, then the expressions of components of the Considering the processes of manufacturing enterprise design, plan, technology, manufacture and etc, it analyses the composition and interdependence of enterprise information system data in this paper. Emphasizing the technical and process section data, analyzing these data’s source, attribute and outgoing. It creates an integral information system basic data model, obtains a system overlap model of these kinds of source data acquisition, provides a settle method for source data incomplete, inaccurate, and substandard of the manufacturing enterprise information system.
