摘 要：In recent years,virtual proving ground（VPG） technique has been widely used in vehicle multi-body dynamics *** paper mainly focuses on the method to construct the digital roads incorporated in the virtual proving *** first,the Mobile Road Scanning System was introduced to acquire point clouds of the physical test roads of an actual proving ground located in southwest of ***,considering both road characteristics and development requirements,a CRG road surface model construction methodology was *** the end,digital surface models of the physical test roads were constructed and coupled in full-vehicle *** a result,the simulation based on the proposed method can predict the external loads of wheel parts under various loading cases,by comparing with load data acquired by *** consequence,our research will assist in providing an efficient tool for the analysis of vehicle system/sub-system loads.
