THE APPLICATION OF IMPROVED RSM IN SHAPE OPTIMIZATION OF TWO-DIMENSION CONTINUUM

SUI Yun-kang , LI Shan-po (Numerical Simulation Center for Engineering, Beijing University of Technology, Beijing 100022, China)  
RSM is used to establish models in shape optimization for two-dimension continuum by solving sensitivity of constraint conditions approximately, that is, complicated response function in terms of design variables can be fitted according to the responses of structural analysis. The error between the fitting value and the structural response value at the design point will affect precision of optimization. This paper provides an improved method that fitting accurately at the central design point. The examples demonstrate that it is a feasible and efficient method.
