Software development of plant rapid propagation digital model and intelligent management platform;

To solve the analysis of complex assembly dimension-chains efficiently,a new method,dimensional element-chain analysis(DECA),for the assembly dimension-chain analysis is presented based on products' digital models and parameter-driven technique.

Based on this,a method is found out by which the whole theodolite system is divided into the associated disciplines models,several modeling software s functions are analyzed,and a final integration digital model from these concurrent tasks is completed in the virtual simulation environment.

The state monitoring and analysis method of a hydroturbine governor based on digitized models is presented to meet the requirements of state based maintenance of facilities.

Using the compound modeling technology of UG software to carry on the 4J34 diesel engine body diecasting die design, established the 3D digitized model that the parametrization actuation.
