Rigorous imaging geometry model of spaceborne linear array CCD sensors
The fractional geometry model of porosity and permeability was developed based on fractional Kriging interpolation principles.
On this basis of geometry model and assembly model, this model integrates design parameters of the parts, constraint relationship of the parameters, force situation, mechanics characteristics.
Vehicle's geometry model is formed, of which the shell structure is the main skin and steel structure made by welding.
According to geometry model characteristic of shaft and cylinder of steam turbine, a finite element method model of shaft and cylinder was set up.
Then the solid geometry model is entered into ANSYS to do the pre-treatment of FEA. It is disassembled by ten-noded tetrahedron elements.
Firstly, the error of fit must be defined for nonlinear least-square fitting of generalized geometry model. Then the nonlinear optimization algorithm can be used to obtain the optimum solution.
Data segmentation is a key process in reverse engineering geometry modeling.
