Research of CAx integration based on unit model

the network structure of the gas system is made up of gas pipeline network and unit model.

According to the ball mill pulverizing process motion character s basic causality,a structure decentralized model is built which is consisted of six unit models,three causality chains and four inter-chain associations.

According to the field expert knowledge about prediction model unit selection in the miner al deposit statistics prediction, this paper designs and realizes an expert system for model unit selection and its consultation medium by GURU expext system tool and C program language.

Acertain numbers of model units with a precise quantity of reserves,are the basis for the establishment of the models for prediction of mineral resource potentiality.

Based on the fiber element model and layered shell element model developed and validated by the authors,this paper establishes the numerical model for space concrete frames under fire.

At present, for non-linear finite element method of reinforced concrete, according to simulative methods, element models can be divided into three kinds: separate model, combined model and integral model.

Based on the HappleKuwabara cell model, the SIMPLE algorithm and the fourth order RungeKutta algorithm have been employed to carry out the simulation of the flow field around the fiber and the single fiber efficiency.
