Secondly, based on general FEM theory, this paper has discussed FEM of matchboard cement concrete pavements with and without joints and explained three-dimensional FEM of cement concrete pavements.

Based on lots of literature and information, this paper has engaged in deep studies and brought forth a new kind of matchboard cement concrete pavement. Firstly, based on the theory of elastic thin slab and elastic subgrade, this paper has discussed the strong points and weaknesses of existed mechanics models of cement concrete pavements. Then, integrating each model's strengths and considering the practical conditions, this paper has put forward reasonable simulating models as well as basic mechanics hypothesis.

Thirdly, with FEM analysis software ANSYS, this paper has fulfilled appropriate pavement FEM models. Selecting right loading locations and parameters, this paper has simulated contact behaviors of limited dimension cement concrete pavement with joints afterwards. The mechanics response results and load transfer ability results of matchboard joints have obtained and the effect of reinforcing steel bars has gained too.

The information integrated pattern based on PDM/PLM in the course ofmanufacture is put forward. Under the constraints of building CAPP platform, thearchitecture of CAPP platform is established. The models of decision making andfunction for process planning are given. Then the development means of CAPP basedSmarTeam are extracted.3. The structure of modular product life cycle is established. Toward the divisionand planning of the General Modules oriented product family, theCAD/CAPP integrated model of flexible module based on feature and CAD/CAPPmapping model based on process planning match board are set up. The keytechnologies of Solidworks/SmarTeam/CAPP integration are studies.4. From the point of view of process match board and step match board, theprocess of creating to process planning match board is studied. As an example, themachining process planning of up beam of hydraulic press machines is used tointroduce the establishment of process planning match board by means of inferencebased on expert knowledge. The organize model about the process planning matchboard oriented product family is brought forward.5. The multi-decision methods of CAPP system based on analytic hierarchy aregiven.. On the basis of uniform data model, the sub-machining process planning ofpart is auto-created by means of analytic hierarchy, The step decision methods basedon AHP is put forward.6. For the design/manufacture information in the course of product life cycle, thetree structure based on Object-Oriented and static model based UML are founded. Themethod of establishing design/manufacture information management system isbrought forward. The commercial PLM software—SmarTeam is regarded asdevelopment platform, on basis of which, the design/manufacture informationmanagement system is built, and the multi-view mapping technique ofdesign/manufacture information model is studies.7. A computer-aided CAPP platform based on PDM/PLM is founded, and itsstructure, function, work flow is illustrated. Some example of the system areintroduced.
