Effect of the Installation of Partition Wall in High Strength Thin-Walled Square Tube on Axial Collapsing Behavior

高強度角筒部材の軸圧潰変形挙動に及ぼす隔壁追加の影響

By using FEM and Drop Weight Test, the effect installing a partition wall in the cross section of a thin-walled square tube on axial collapsing behavior was quantitatively clarified to ensure high crash energy absorption．Installing a partition wall into cross section of thin-walled square tube resulted in controlling out of plane displacement within cross section of one as high tensile strength sheet steel is used. As a result, a thin-walled square tube with high energy absorption was confirmed. In summarized, the guideline which can control the axial collapsing behavior about a thin-walled square tube by installing a partition wall was proposed.
