Strength & Stiffness Estimation for Center Frame of Low-Floor Vehicle
For the designed center frame of low-floor vehicle to have light-weight sandwich structure with glass fabric/epoxy resin skins, aluminum honeycomb cores and steel inner-frames, regression equations for maximum equivalent stresses (Von-Mises stress) and maximum vertical deflection were proposed by finite element analysis. On the basis of the analysis results, the strength and stiffness for the center frame were discussed in this paper.
