| Abstract: | The quantitative analysis and performance optimization of the effect of thin-walled beam section parameters on its bending and torsion stiffness are very important.Taking the Stiffness Mass Efficient(SME) into consideration,the analysis of typical closed and open section beam,relation between sectional parameters of thin-walled beam and its SME was derived.FEM simulation was carried out in HyperMesh and proved that the theoretical derivation was correct.Then,the stiffness optimization based design principle... |
