Study on energy models and constraint relations in discrete manufactures

According to the actual working situation of fully mechanized coal face, the running constraint relation between powered supports and shearer, and relation between powered supports and scraper conveyor were analyzed.

A representation model of the drawing knowledge is established by embodying geometry and knowledge constraint relations in engineering drawings, thus improving the engineering knowledge system and realizing an integrated engineering intelligent CAD system of struc.

Based on theoretic analysis and model tests,it is pointed out that there is a constraint relationship between the sensitivity and multiplexing capability of distributed fibre optic sensors for crack monitoring,i.

It presented the canonical representation of 2D geometric elements such as line and circle and their common constraint relationships first,then recognized the underlying relationships among them in accordance with constraint recognition maxima and.

In this paper,destruction experiment on different semi-rigid connection made of rolled angle was performed under repetitive loading,through which the constraint relationship of connection,hyster.

This paper combines constrained relationship with RNN queries and some methods are proposed.

The constrained relationship of the x and y was calculated for In Ga As P which 1-x xy 1-y matched to GaAs substrate, and the results was verified.

And six key points of curves parametric design are proposed that include the classification of curves, the extraction of curves dimension, the induction of basic constraint relations, the geometrical and topological structure representation of curves and surfaces, the geometric reasoning method for constraints, and the satisfaction way for constraints.

This system can be available for the intellingence parametric designing of the master shaft ensemble of the numerical control machine tools on the bases of automatically recognizing and collecting both the characteristic relations and the constraint relations of the graph.

In order to reduce the parameter number evaluated by GA and improve the convergent speed of GA,the constraints between the parameters of the cylindrical geometry character are appended.

This paper presents a method based on W3C XSLT standard,by which the constraints between nodes in XML documents can be validated.

Now VEADAM mainly implements virtual assembly which includes system architecture, interface between pro/E and virtual environment, constraint, cooperation, multimodal human computer interaction.
