Finite Element Analysis of Full-monocoque Body of a 12 m Fuel Cell Bus
DIAO Guohu,FEI Youxia
Abstract: Taking a newly developed 12 m fuel cell bus as an example,this paper uses Patran+Nastran soft-ware to carry out finite element analysis of its full-monocoque body,mainly analyzing the stress of typical working conditions such as vertical load,bending and twisting,turning and braking conditions,puts forward specific improvement measures for the advantages in the structure design,to provide reference for the structural design of fuel cell bus in the future.
Key words: full-monocoque body; finite element analysis; fuel cell; structure design
