Characteristic Analysis of Side Impact of MDB and Rigid Column of Automobile

Abstract

Aimed at the design mathematical modeling of a certain brand of automobile, the finite element modeling of the whole car was built with the help of HyperWorks software based on FEA principle. According to the C-NCAP and E-NCAP principles and in the environment of LS-DYNA, the paper did a computer simulation of the side MDB impact and side rigid column impact to the car. From the perspectives of the invasion, invading velocity and invading acceleration of pillar B and the door, as well as the whole car conversion of energy, the paper evaluated the effects of the two impact simulation experiments and contrasted the simulation results of these two impact experiments, which helped study the different impact characteristics and further improve the side impact security of this car.
