Title:
METHOD AND DEVICE FOR ANALYSIS OF SHAPE OPTIMIZATION
Document Type and Number:
WIPO Patent Application WO/2014/119176
Kind Code:
A1
Abstract:
When optimizing the part of a structure model having a moveable part using planar elements or three-dimensional elements, a design space is configured consisting of the portion to be optimized of the moveable part, and, in the configured design space, an optimization block model is generated for performing optimization analysis processing, said model being configured from three-dimensional elements. The generated optimization block model is combined with a structure model and material characteristics are configured in the optimization block model. Optimization analysis conditions for calculating an optimal shape are configured in the block model, and mechanism analysis conditions for performing mechanism analysis are configured in the structure model combined with the optimization block model. On the basis of the configured optimization analysis conditions and mechanism analysis conditions, mechanism analysis is performed on the optimization block model to calculate an optimal shape of the optimization block model.
