METHOD FOR EVALUATING FRONT FACE COLLISION PERFORMANCE OF FRONT SIDE MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a method for evaluating the front face collision performance of a front side member capable of reproducing axial compression flexure deformation like a case where a full vehicle is used by a front face collision test using a partial model. ! SOLUTION: A method for evaluating front face collision performance evaluates a front side member having a bumper beam 2 and left and right side members 1. An inertia mass 4 is rotatably supported by a fixed shaft 3 installed at a position away from the extension line of the side member 1. Impact is applied by an impact head 8 onto the forward end of the side member 1 under a state where the inertia mass 4 being an evaluation object is fixed at the rear end of the side member 1. Thus, axial compression and flexure deformation can be continuously generated in the side member 1. ! COPYRIGHT: (C)2015,JPO&INPIT
