Construction of design guidelines for automotive frame shape based on datamining approach and mechanical analysis

Jun 4, 2024 | 3:00 - 3:25 PM

In order to reduce CO2 emissions when driving a car, it is necessary to reduce running resistance by reducing the weight of the car body. The vehicle body is required to have the function of securing the occupant's survival space in the event of a collision, and in general, weight reduction and strength of the vehicle body frame are in conflict with each other. Therefore, structural design technology to suppress cross-sectional collapse is important.
In this report, optimization of the cross-sectional shape of a car body frame formed by thin-walled high-strength steel plates was performed to improve the bending strength of the frame. The validity of the optimal solution was verified by comparing the optimization results with multivariate analysis and buckling theory.
