Influence of front shape on crosswind aerodynamic loads of heavy-duty truck: A numerical case study

摘要：

Research was done on the crosswind aerodynamic loads of three different front shape heavy-duty trucks by the method of numerical simulation. According to the research, the side force and the rolling moment of truck change slightly, but the drag and yawing moment changes dramatically when running in strong crosswind with different front shapes. The conclusions were drawn from discussion that the long head heavy-duty truck has the least yawing moment among the studied trucks so it has the best driving stability correspondingly.
