摘要

PROBLEM TO BE SOLVED: To provide a surface shape design method of an automobile outer plate component excellent in dent resistance as well as the component excellent in dent resistance designed by this method.;SOLUTION: The average distance Dave of at least four points where load positions have short distances to a junction point of mastic 3 of an automobile outer plate component is obtained, and then a plastic strain generating load Pd is calculated by variously changing an input value of the radius of curvature in a dent resistance investigation model using a panel 5 having a diagonal length DI of 1.6×Dave to 2.4×Dave and a radius of curvature in a single direction. Then, a radius of curvature Rmin in which Pd becomes minimum is derived from the relation between the calculated Pd and the input value of the radius of curvature, and a surface shape design of the automobile outer plate component is carried out, while taking the Rmin into consideration.;COPYRIGHT: (C)2012,JPO&INPIT
