To perform a collision performance evaluation test in a deformation mode for crushing a cross section of an evaluation member that corresponds to an automobile structure component and has a hollow cross section extending in a longitudinal direction by a simple method.SOLUTION: When performing a collision performance evaluation test of an evaluation member that corresponds to an automobile structure component and has a hollow cross section extending in a longitudinal direction, the evaluation member is clamped so as to crush a cross section of the evaluation member by a support part for supporting the evaluation member along a longitudinal direction by abutting on the evaluation member along the longitudinal direction of the evaluation member and a punch that travels in an intersecting direction of the longitudinal direction of the evaluation member and inputs a load into the evaluation member, and at least a part of the support part exists in a region in which a contact region of the punch in the evaluation member extends in a traveling direction of the punch.SELECTED DRAWING: Figure 2
【課題】自動車用構造部品に対応する、長手方向に延在する中空断面を持つ評価部材の、断面を圧壊させる変形モードでの衝突性能評価試験を簡便な方法で行うことにある。【解決手段】自動車用構造部品に対応する、長手方向に延在する中空断面を持つ評価部材の衝突性能評価試験を行うに際し、前記評価部材の長手方向に沿ってその評価部材に接触することでその長手方向に沿って前記評価部材を支持する支持部と、前記評価部材の長手方向に対する交差方向に移動してその評価部材に荷重を入力するパンチとで前記評価部材の断面を圧壊させるように前記評価部材を挟圧し、前記評価部材における前記パンチの接触領域を前記パンチの移動方向に延長した領域に前記支持部の少なくとも一部が存在することを特徴とする。【選択図】図2
