| Abstract: | Road excitation load is generated and its characteristics are tested using Matlab,and by combining with vehicle multi-body dynamics model,the excitation load for vehicle body fatigue analysis is obtained.The dynamic stresses of vehicle body are calculated by transient time domain approach and the fatigue locations of fuel cell bus body are identified with their fatigue life predicted by utilizing software MSC/Fatigue.The analysis provides references for structure design and modification. |
