Body In-white Design of Fuel-cell Vehicle Based on the FEM

摘要

Body strength is a key factor of car-body performance.Nowadays,the structural analysis method of car hody includes the numerical simulation and experimental method,the main method of modern numerical simulation is the finite element method.This paper is about the strength analysis of fuel-cell car-body with the finite element method which mainly relates to the simplification of the finite element model,the rational distribution of load,and the selection of the relevant conditions.We put forward the improvement program by analyzing the body strength of the fuel-cell car.
