Lightweight Analysis of Automotive Anti-Collision Materials Based on Equal Energy Absorption Strategy

Abstract:

A new method is proposed to determine the maximum energy that absorbed by axial pressured thin wall tube. Three typical collision speeds are selected, which are low speed at 30km/h, medium speed at 60km/h and high speed at 90km/h. This paper also calculates the strain rates under different automotive collision conditions. Finite element software ABAQUS was used to investigate the effect of lightweight when circular thin wall tubes with different materials absorbing maximum and equal energy. The materials for thin wall tubes are high-strength steel, aluminum alloy and plain steel. The effect of lightweight of different material tubes in low strain rate, medium strain rate, and high strain rate can be obtained using the equal energy absorption strategy. The weight that reduced by high-strength steel tube and aluminum alloy tube is higher than that of plain steel tube, at all three strain rates.
