The paper presents the detailed finite element model of certain car body, which is reasonably simplified according to actual loading conditions. First, frequency response is analyzed by means of modal method with software MSC. Nastran, secondly, the correlation of spectrum loading is analyzed, by the treatment of practical loading; then the fatigue life analysis of correlated and uncorrelated loading of car body is obtained based on the theory of Palmgren-Miner cumulative fatigue damage, in MSC. Fatigue software environment; finally, the impact of correlation of loading on the fatigue life of car body is represented. The theoretical results are in agreement with the experimental ones. Some ameliorated measures are proposed to the unsubstantial regions.
