In order to avoid the reconstruction of CAD model and integrate design intent and manufacturing process into optimal result during structural shape and topology optimization of continuum solid model, a novel method of shape and topology optimization directly on CAD solid model is presented.Firstly, in terms of the characteristic of CAD geometric model and CAE mesh model, a scheme of CAD/CAE integration is proposed.And then, based on the gradual change of CAD model during optimization, the reanalysis approach is introduced to improve the efficiency of structural analysis.On the other hand, due to the fusion of product design intent on direct modeling technique is by means of geometric constraints, the method of variational geometry is adopted to analytically compute the parameter sensitivity with respect to objective function.Finally, several numerical examples are demonstrated to prove the feasibility of the proposed method.
