Research on Dynamic Load of Belgian Event Based on VPG 2019-01-0170
The durable load spectrum of the physical proving ground is the necessary input for fatigue life analysis of vehicle parts and components. It is usually obtained by vehicle road load acquisition and load decomposition in the industry, and Virtual Proving Ground (VPG) is gradually replacing this technical route. The belgian road is the typical event in durability test, in this paper, the flexible body and FTire model are applied to the multi-body dynamics model in order to improve the simulation accuracy. The result shows that all the wheel six-component force, shock absorber displacement and axial force acquired by VPG simulation have excellent correlation with real vehicle data. It is also proved that the virtual proving ground technology is a reliable and effective method to obtain the durable load spectrum in the early stage of development.
