SHAPE DEFORMATION MODE GENERATION SYSTEM, SHAPE OPTIMIZATION ANALYZING SYSTEM AND RECORD MEDIUM IN WHICH PROGRAM USED FOR THE SAME IS RECORDED

摘要

PROBLEM TO BE SOLVED: To execute analysis of an optimal shape with high accuracy and economically by dividing a structural shape model into small areas, classifying each small area into a fixed surface and a variable surface in an optimized shape, calculating deformation of the entire structure by optionally applying a virtual pseudo-load for every area, and using the deformed shape as a shape deformation mode data. ;SOLUTION: An analysis model previously generated base on an instruction by an operator is divided into plural small areas by a dividing part 9a. The fixed surface and the variable surface are set in the analysis model at each of plural small areas divided by the dividing part 9a based on the instruction by the operator by a fixed/variable surfaces setting part 9b. Plural loads to perform shape deformation to the analysis model are optionally set based on a random number, etc., and the deformed shape of the entire analysis model in all combinations of each of the settings is calculated by a deformation shape pattern generating part 9c. The deformation shape calculated in this way is used as a designing variable in analysis of the optimal shape of the structure.;COPYRIGHT: (C)1999,JPO
