| Abstract: | Using the orthogonal design method and LS-DYNA which is a kind of collision calculation software to get the dispersed and comparable experiment data points,the problem of traditional single-objective optimization design was solved.As it optimizes one objective and the defect of low accuracy caused by matrix singular while calculating the regression model using the least squares in the traditional response surface method,the method of differential evolution without constraints was quoted for the construction... |
