ABSTRACT:– In this project the objective is to improve the B-pillar that is made of mild steel (192), in term of specific energy absorption and weight reduction. The conventional material mild steel needs to be change to other material that can absorb more energy during collision and reduce the injury level of driver and occupant. Three Side pole impact test will be conducted using ANSYS simulation software for three materials Mild steel (192), aluminum AA (6060T40) and hot press formed Usibor (1500P). side pole impact test will be carried out according to FMVSS 214 role and regulation car moving at 32.2 km/h (20 mph) at an angle of 75 degrees crashes into a fixed rigid pole that is 254 mm diameter.
The following are the result for the simulation in result of directional deformation
Throughout the tree materials Usibor (1500P) B-pillar had the maximum energy absorption that reach 414.07 KJ/Kg. aluminum AA B-pillar (6060T4) comes in second place with 299.52 KJ/Kg. benchmark model mild steel (MAT192) had the lowest energy absorption with result of 212.48 KJ/Kg. Using Usibor (1500P) in B-pillar lead to reduction in weight that reach about 53.27%. in the other hand aluminum AA (6060T4) weight reduction reached 51.54% compared with commercialize B-pillar mild steel (MAT192).
Usibor (1500P) showed great energy absorption and helped in reducing the weight of Bpillar and it will be the perfect selection in replacing the benchmark model B-pillar mild steel (MAT192).
