| Abstract: | In order to reduce the mass of car body B pillar,improve its side crashworthiness and simplify the manufacturing process,a method using the hot formed B pillar was proposed.The method produces the B pilllar reinforcement panel with uniform thickness and varying yield strength by different cooling rate at hot forming.To make the distribution of the yield strength in the hot formed B pillar reasonable,an optimization design was performed by the finite element analysis.Taking a certain car as an example,an opt... |
