Compared Vehicle Body Fatigue Analysis Based on VPG and Experimental Road Load Data

In this paper, a vehicle body fatigue analysis is performed by using virtual road load data from virtual proving ground. Comparison of fatigue results based on virtual road load data and tested road load data is conduct. By comparing the results, the calculated body damage areas are found very similar and can be accepted in engineering. Therefore, tested road load data can be partly replaced with load data from virtual proving ground at early period of the project. The development time and test costs can be reduced accordingly.
