For the coupling tasks, a dynamic constraint satisfaction strategy is put forward.

This paper introduces the 3D simulation based on VBA and constrains driving,by the simulation for the feeding of a drill press in the environment of Inventor assembly.

Considering the flexible effect of the harmonic retarders,the style of dynamic constraint of the flexible beam during control was analyzed;then,the modal frequency and vibration shapes related to the control parameters and hamonic retarder s rigidity parameter were obtained.

This paper constructs the fuzzy-valued dynamic constraint concept networks on the theoretical basis of the fuzzy sets and the semantic networks,introduces the basic construction method of this concept network,and puts forward the text analysis algorithm based on the concept network.

On the theoretical basis of the neural networks and the semantic networks,this article constructs the dynamic constraint concept networks,introduces its characteristic of constraint,dynamic and inheritance,and puts forward the model of knowledge retrieval based on the concept networks and the heuristic dynamic retrieval algorithm.

based on an analysis of the effect of the kinematic constraint on system s stochastic observability.

A method to solve the compatibility equation of distortion indirectly is put forward based on the kinematic constraint relation.

This paper studies 35 examples by FEIS FEA PROGRAM written by author and proves that the rotational restraint of column base which exists in effect does not affect the intension of column root decide by the code and the method in the code is safe.

A reinforced concrete beam with restraint stiffness is selected for the fire endurance analysis,the effect of the axial and rotational restraint stiffness ratios,and the height-span ratio on the fire resistance of the reinforced concrete beam is primarily studied.
