Design of Aluminum Alloy Anti-Collision Beam for Passenger Cars
Taking the aluminum alloy front anti-collision beam assembly of a certain passenger car as an example,under the premise of ensuring similar weight,CAE analysis was conducted on the main beams and energy absorption boxes of different sections to obtain the performance of the single piece structure,and conduct CAE analysis on the assemblies of 6 different combinations to obtain the optimal structural combination.The result shows that the structure of the"目"shaped section main beam is optimal,and the structure of the"octagon with stiffener"section energy absorption box is optimal.Under the three-point bending condition of the assembly,the combination of the"目"shaped section main beam and the"octagonal with stiffener"section energy absorption box is optimal.Under the condition of flat compression of the assembly,the combination of"目"shaped section main beam and"octagonal with stiffener"section energy absorption box has the optimal energy absorption value,and the combination of"日"shaped section main beam and"十"shaped section energy absorption box has the optimal support reaction force.
