Space frame structure of cars made in aluminium are considered to use aiming at light weights and much energy absorbing members. In this study, gate-shaped side members with notches are of interest to control the crush modes and increase the absorbing energy in collision. Nonlinear collision analysis is done by making use of FEM software. Twelve models with notches at different positions and two kinds of depths of notches are considered here for three kinds of collision speeds. Based on collision analysis of those models, the energy absorbing response surfaces with respect to the positions and depths of the notches are made by the design of experiment using orthogonal arrays. Optimum positions and depths are found on the response surface by the SQP (Sequential Quadratic Programing) method and the results are examined.
